ABBREVIATIONS

Abbreviate the following:
Titles before names:
Mrs., Mr., Ms., Prof., Dr., Gen., Rep., Sen., St. (for Saint)
Notice that Miss is not an abbreviation, so we don't put a period after it. Ms. is not an abbreviation, either, but we do use a period after it - probably to keep it consistent with Mr. and Mrs.

The plural of Mr. is Messrs. (We invited Messrs. Carter, Lincoln, and Ford.) The plural of Dr. is Drs. (We consulted Drs. Carter, Lincoln, and Ford.) The plural of Mrs. is Mmes or Mmes. (with or without the period).

In most formal prose, we do not use titles, abbreviated or otherwise, with individuals. Ms. Emily Dickinson is simply Emily Dickinson, and after the first use of her full name, Dickinson will do (unless we need Emily to avoid confusion with other Dickinsons).

The abbreviations Rev. and Hon. (for Reverend and Honorable) are not, strictly speaking, titles; they are adjectives. In informal language or when we're trying to save space or make a list, we can write Rev. Alan B. Darling and Hon. Francisco Gonzales. In formal text, we would write "the Reverend Alan B. Darling" and "the Honorable Francisco Gonzales" (i.e., it's not a good idea to abbreviate either Reverend or Honorable when these words are preceded by "the"). Incidentally, we cannot say "We invited the reverend to dinner" and only a cad would invite "the rev."

Titles after names:
Sr., Jr., Ph.D., M.D., B.A., M.A., D.D.S.
These are standard abbreviations, with periods. The APA Publication Manual recommends not using periods with degrees; other reference manuals do recommend using periods, so use your own judgment on this issue. All sources advise against using titles before and after a name at the same time (i.e., she can be Dr. Juanita Espinoza or Juanita Espinoza, PhD, but she cannot be Dr. Juanita Espinoza, PhD). And we do not abbreviate a title that isn't attached to a name: "We went to see the doctor (not dr.) yesterday."

The Chicago Manual of Style recommends not using a comma to separate the Jr./Sr./III from the last name, but you should follow the preferences of the indivdual if you know those preferences. If you list a "junior" with his spouse, the "Jr." can go after both names, as in "Mr. and Mrs. Arthur C. Banks Jr." or "Mr. Arthur C. Banks Jr. and Gloria Banks - but not Arthur C. and Gloria Banks Jr. You should avoid using a "Jr." or "Sr." when you have only the last name - Mr. Banks Jr.

Have you ever run across an acronym or abbreviation and not known what it means? Try using the Acronym Finder. Just type in the letters and click on Search. Out of a database of over 190,000 abbreviations and acronyms, the Finder will probably discover what you're looking for.

Names of
• familiar institutions - UConn, MIT, UCLA, CIA, FBI, NATO
• countries - U.S.A., U.K.
• corporations - IBM, CBS, NPR, CNN, ITT
• famous people - LBJ, FDR, JFK, MLK
• very familiar objects - TV, VCR, CD-ROM.

Notice that U.S.A. can also be written USA, but U.S. is better with the periods. Also, we can use U.S. as a modifier (the U.S. policy on immigration) but not as a noun (He left the U.S. U.S.A.).

Terms of mathematical units: 15 in., 15 ft, 15 kg, 15 m, 15 lb

Generally, you would use these abbreviations only in technical writing. There is a space between the number and the abbreviation. Notice that we do not put an s after such abbreviations even when the plural is indicated. Also, we do not use a period with such abbreviations except for in. when it might be confused with the preposition in.

When the term of measurement is used as a modifier, we put a hyphen between the number and the term of measurement: a 15-ft board, a 6-lb line, etc.

Long, common phrases, such as IQ (Intelligence Quotient), rpm (revolutions per minute), mph (miles per hour), and mpg (miles per gallon).

Such abbreviations are acceptable even in formal academic text and may be used without periods.
Words used with numbers: He left at 2:00 a.m. She was born in 1520 B.C.
Either lower or upper case letters can be used with A.M., a.m., P.M., p.m. The abbreviation B.C. (before Christ) is used after the date; A.D. (anno domini, "in the year of the Lord") appears before the date. The abbreviations B.C. and A.D. are sometimes replaced with B.C.E. (before the common era) and C.E. (common era), both used after the date (although one must add that those abbreviations are neither widely used nor commonly understood). Sometimes you will see 790 BC and AD 78 written without periods and written in SMALL CAPS. Note that many style books are now recommending SMALL CAPS for all appearances of acronyms, such as NAACP or NCAA. The effect of this practice is to allow the acronym to blend more smoothly with the rest of the text.

It is considered bad form to use these abbreviations without a specific number attached to them: "We'll do this in the a.m." or "We'll do this tomorrow a.m."
Common Latin terms: etc. (et cetera - and so forth), i.e. (id est - that is), e.g. (exempli gratia - for example), et al. (et alii - and others).

The abbreviation i.e. (i.e., that is) is often confused with other abbreviations (e.g., e.g.). The i.e. generally is used to introduce matter that is explanatory as opposed to being the name of an example or list of examples. If you can say for example as a substitute for the abbreviation, you want to use e.g., not i.e. Do not italicize or underline these abbreviations. Most sources recommend avoiding the use of Latin abbreviations except within parenthetical notes and some sources say not to use Latin abbreviations at all (use the English terms instead) except within citations or reference lists. Good advice.

The Chicago Manual of Style recommends using a comma after i.e. or e.g. in order to set off those abbreviations as introductory modifiers. Other resources say not to bother with the comma, but the comma makes good sense.

Except in the business of formally citing material you've used in research, it's a good idea not to use et al. when you mean "and others." And don't use etc. as a lazy person's way of getting out of work. Spell out the word versus unless you're reporting game scores, when you would use vs.; when you're citing legal documents, use the abbreviation v.
Names of states and territories in references and addresses, but not in normal text. Abbreviations accepted by the U.S. Postal Service (including abbreviations for words like Boulevard and Alley) are listed online. Do not use state abbreviations simply to save time or space except in an address on an envelope or list. We do not use periods with state abbreviations: CT, NY, NJ. We use D.C. after the name of the city within the District of Columbia: Washington, D.C.; the APA Manual does not use periods with DC. The U.S. postal service, incidentally, does not insert a comma between the city and the abbreviated state name: Hartford CT, Portland OR - at least not in the addresses on envelopes.

Abbreviate "Saint" in U.S. place names, as in St. Louis and St. Petersburg, Florida, and the St. Lawrence River. For the same word in other countries, you might have to consult a good dictionary (one that contains place names): St./Saint Martin's in the Fields, Saint Moritz, Saint Lucia, Mont-Saint-Michel, Saint Petersburg (Russia). When the word Saint is used to refer to a holy person, spell out the word - Saint Theresa, Saint Francis of Assisi. If an institution is named after a saint, spell out the word Saint unless you have some reason to save space - Saint Francis Hospital, Saint Joseph College, Saint Joseph's University. It is wise, as always, to consult the actual institution. Colleges, universities, and hospitals named after Saint Mary are about evenly divided between St. and Saint, but in formal situations, Saint seems to be favored more frequently.

Don't abbreviate the following:
(In formal academic prose it is considered bad form to abbreviate words simply to save space, time, or energy.)

• Words such as through (thru), night (nite).
• Days of the week or months of the year (in the normal flow of text).
• Words at the beginning of a sentence.
• People's names such as Chas. (for Charles) or Jas. (for James), unless those abbreviations have come to be accepted as nicknames for those particular individuals.
• States' names such as Mass. (for Massachusetts) or Conn. (for Connecticut). When appropriate (as in the addresses for envelopes), use the U.S. postal service's approved two-letter abbreviations: MA, CT (without periods).
• Courses such as econ (for economics) or poli sci (for political science).

Spacing and Periods
Abbreviations of units of measure are written without periods (with the exception of "in" when it could be confused with the preposition). We use periods for most lower-case abbreviations such as e.g. and i.e. and c.o.d. For very common abbreviations, leave out the periods, as in rpm and mph. When an abbreviation with a period ends a sentence, that period will suffice to end the sentence: He lives in Washington, D.C. Suffixes for people's names require periods: Joe Smith Jr. lives in Erie. In formal text it is not a good idea to abbreviate military titles - Lieutenant Colonel Chester Piascyk - but in informal text Lt. Col. Chester Piascyk would be acceptable. (Note the space after "Lt.") Academic degrees can be written with periods or not, but don't insert spaces - Ph.D. or PhD, M.B.A. or MBA - within the degree.

People's initials are usually followed by a period and a space - W. E. B. DuBois - but you need to be careful that a line-break doesn't come in the middle of someone's initials. (You can impose what is called a "forced space" or "non-breaking space" by holding down the option key while you hit the space bar.) You will find exceptions to this rule in the way that some companies write their name: JCPenney (no spaces or periods), L.L. Bean (no space in the initials), etc. In normal text, writers can safely ignore corporate aberrations in spacing and capitalization. (Some editors write Harry S Truman without a period after the "S," because the initial didn't really stand for anything, but the Truman Presidential Museum and Library contends that that practice is silly. Still, you will often find Truman's name written sans period in highly regarded places.) When a person's initials stand alone - either as a nickname, "Come here, JT!" - or as a common shortcut - JFK (for John Fitzgerald Kennedy) or LBJ (for Lyndon Baines Johnson) - type them without spaces or periods. Professional designations such as CPA (Certified Public Accountant) or CLU (Certified Life Underwriter) are separated from the last name with a comma and are written without spaces or periods, as in Bertha Bigknot, CPA, unless the designation is accompanied by an academic degree, as in Foxy Reynard, Ph.D., C.L.U.

HELPING AND MODAL AUXILIARY VERBS
Helping verbs or auxiliary verbs such as will, shall, may, might, can, could, must, ought to, should, would, used to, need are used in conjunction with main verbs to express shades of time and mood. The combination of helping verbs with main verbs creates what are called verb phrases or verb strings. In the following sentence, "will have been" are helping or auxiliary verbs and "studying" is the main verb; the whole verb string is underlined:
• As of next August, I will have been studying chemistry for ten years.

Students should remember that adverbs and contracted forms are not, technically, part of the verb. In the sentence, "He has already started." the adverb already modifies the verb, but it is not really part of the verb. The same is true of the 'nt in "He hasn't started yet" (the adverb not, represented by the contracted n't, is not part of the verb, has started).

Shall, will and forms of have, do and be combine with main verbs to indicate time and voice. As auxiliaries, the verbs be, have and do can change form to indicate changes in subject and time.
            • I shall go now.
            • He had won the election.
            • They did write that novel together.
            • I am going now.
            • He was winning the election.
            • They have been writing that novel for a long time.

Uses of Shall and Will and Should
In England, shall is used to express the simple future for first person I and we, as in "Shall we meet by the river?" Will would be used in the simple future for all other persons. Using will in the first person would express determination on the part of the speaker, as in "We will finish this project by tonight, by golly!" Using shall in second and third persons would indicate some kind of promise about the subject, as in "This shall be revealed to you in good time." This usage is certainly acceptable in the U.S., although shall is used far less frequently. The distinction between the two is often obscured by the contraction 'll, which is the same for both verbs.
In the United States, we seldom use shall for anything other than polite questions (suggesting an element of permission) in the first-person:

"Shall we go now?"
"Shall I call a doctor for you?"

(In the second sentence, many writers would use should instead, although should is somewhat more tentative than shall.) In the U.S., to express the future tense, the verb will is used in all other cases.
Shall is often used in formal situations (legal or legalistic documents, minutes to meetings, etc.) to express obligation, even with third-person and second-person constructions:

The board of directors shall be responsible for payment to stockholders.
The college president shall report financial shortfalls to the executive director each semester."

Should is usually replaced, nowadays, by would. It is still used, however, to mean "ought to" as in

You really shouldn't do that.
If you think that was amazing, you should have seen it last night.

In British English and very formal American English, one is apt to hear or read should with the first-person pronouns in expressions of liking such as "I should prefer iced tea" and in tentative expressions of opinion such as

I should imagine they'll vote Conservative.

I should have thought so.

Uses of Do, Does and Did
In the simple present tense, do will function as an auxiliary to express the negative and to ask questions. (Does, however, is substituted for third-person, singular subjects in the present tense. The past tense did works with all persons, singular and plural.)

I don't study at night.
She doesn't work here anymore.
Do you attend this school?
Does he work here?

These verbs also work as "short answers," with the main verb omitted.

Does she work here? No, she doesn't work here.

With "yes-no" questions, the form of do goes in front of the subject and the main verb comes after the subject:

Did your grandmother know Truman?
Do wildflowers grow in your back yard?

Forms of do are useful in expressing similarity and differences in conjunction with so and neither.

My wife hates spinach and so does my son.
My wife doesn't like spinach; neither do I.

Do is also helpful because it means you don't have to repeat the verb:

Larry excelled in language studies; so did his brother.
Raoul studies as hard as his sister does.

The so-called emphatic do has many uses in English.

To add emphasis to an entire sentence: "He does like spinach. He really does!"
To add emphasis to an imperative: "Do come in." (actually softens the command)
To add emphasis to a frequency adverb: "He never did understand his father." "She always does manage to hurt her mother's feelings."
To contradict a negative statement: "You didn't do your homework, did you?" "Oh, but I did finish it."
To ask a clarifying question about a previous negative statement: "Ridwell didn't take the tools." "Then who did take the tools?"
To indicate a strong concession: "Although the Clintons denied any wrong-doing, they did return some of the gifts."

In the absence of other modal auxiliaries, a form of do is used in question and negative constructions known as the get passive:

Did Rinaldo get selected by the committee?
The audience didn't get riled up by the politician.

Uses of Have, Has and Had
Forms of the verb to have are used to create tenses known as the present perfect and past perfect. The perfect tenses indicate that something has happened in the past; the present perfect indicating that something happened and might be continuing to happen, the past perfect indicating that something happened prior to something else happening. (That sounds worse than it really is!) See the section on Verb Tenses in the Active Voice for further explanation; also review material in the Directory of English Tenses.
To have is also in combination with other modal verbs to express probability and possibility in the past.

As an affirmative statement, to have can express how certain you are that something happened (when combined with an appropriate modal + have + a past participle): "Georgia must have left already." "Clinton might have known about the gifts." "They may have voted already."
As a negative statement, a modal is combined with not + have + a past participle to express how certain you are that something did not happen: "Clinton might not have known about the gifts." "I may not have been there at the time of the crime."
To ask about possibility or probability in the past, a modal is combined with the subject + have + past participle: "Could Clinton have known about the gifts?"
For short answers, a modal is combined with have: "Did Clinton know about this?" "I don't know. He may have." "The evidence is pretty positive. He must have."

To have (sometimes combined with to get) is used to express a logical inference:

It's been raining all week; the basement has to be flooded by now.
He hit his head on the doorway. He has got to be over seven feet tall!

Have is often combined with an infinitive to form an auxiliary whose meaning is similar to "must."

I have to have a car like that!
She has to pay her own tuition at college.
He has to have been the first student to try that.

Modal Auxiliaries
Other helping verbs, called modal auxiliaries or modals, such as can, could, may, might, must, ought to, shall, should, will, and would, do not change form for different subjects. For instance, try substituting any of these modal auxiliaries for can with any of the subjects listed below.

I you (singular) he we you (plural) they	can write well.

There is also a separate section on the Modal Auxiliaries, which divides these verbs into their various meanings of necessity, advice, ability, expectation, permission, possibility, etc., and provides sample sentences in various tenses. See the section on Conditional Verb Forms for help with the modal auxiliary would. The shades of meaning among modal auxiliaries are multifarious and complex. Most English-as-a-Second-Language textbooks will contain at least one chapter on their usage. For more advanced students, A University Grammar of English, by Randolph Quirk and Sidney Greenbaum, contains an excellent, extensive analysis of modal auxiliaries.

Uses of Can and Could
The modal auxiliary can is used

to express ability (in the sense of being able to do something or knowing how to do something):
He can speak Spanish but he can't write it very well.
to expression permission (in the sense of being allowed or permitted to do something):
Can I talk to my friends in the library waiting room? (Note that can is less formal than may. Also, some writers will object to the use of can in this context.)
to express theoretical possibility:
American automobile makers can make better cars if they think there's a profit in it.

The modal auxiliary could is used

to express an ability in the past:
I could always beat you at tennis when we were kids.
to express past or future permission:
Could I bury my cat in your back yard?
to express present possibility:
We could always spend the afternoon just sitting around talking.
to express possibility or ability in contingent circumstances:
If he studied harder, he could pass this course.

In expressing ability, can and could frequently also imply willingness: Can you help me with my homework?

Can versus May
Whether the auxiliary verb can can be used to express permission or not — "Can I leave the room now?" ["I don't know if you can, but you may."] — depends on the level of formality of your text or situation. As Theodore Bernstein puts it in The Careful Writer, "a writer who is attentive to the proprieties will preserve the traditional distinction: can for ability or power to do something, may for permission to do it.

The question is at what level can you safely ignore the "proprieties." Merriam-Webster's Dictionary, tenth edition, says the battle is over and can can be used in virtually any situation to express or ask for permission. Most authorities, however, recommend a stricter adherence to the distinction, at least in formal situations.

Uses of May and Might
Two of the more troublesome modal auxiliaries are may and might. When used in the context of granting or seeking permission, might is the past tense of may. Might is considerably more tentative than may.

May I leave class early?
If I've finished all my work and I'm really quiet, might I leave early?

In the context of expressing possibility, may and might are interchangeable present and future forms and might + have + past participle is the past form:

She might be my advisor next semester.
She may be my advisor next semester.
She might have advised me not to take biology.

Avoid confusing the sense of possibility in may with the implication of might, that a hypothetical situation has not in fact occurred. For instance, let's say there's been a helicopter crash at the airport. In his initial report, before all the facts are gathered, a newscaster could say that the pilot "may have been injured." After we discover that the pilot is in fact all right, the newscaster can now say that the pilot "might have been injured" because it is a hypothetical situation that has not occurred. Another example: a body had been identified after much work by a detective. It was reported that "without this painstaking work, the body may have remained unidentified." Since the body was, in fact, identified, might is clearly called for.

Uses of Will and Would
In certain contexts, will and would are virtually interchangeable, but there are differences. Notice that the contracted form 'll is very frequently used for will.
Will can be used to express willingness:

I'll wash the dishes if you dry.
We're going to the movies. Will you join us?

It can also express intention (especially in the first person):

I'll do my exercises later on.

and prediction:

specific: The meeting will be over soon.
timeless: Humidity will ruin my hairdo.
habitual: The river will overflow its banks every spring.

Would can also be used to express willingness:

Would you please take off your hat?

It can also express insistence (rather rare, and with a strong stress on the word "would"):

Now you've ruined everything. You would act that way.

and characteristic activity:

customary: After work, he would walk to his home in West Hartford.
typical (casual): She would cause the whole family to be late, every time.

In a main clause, would can express a hypothetical meaning:

My cocker spaniel would weigh a ton if I let her eat what she wants.

Finally, would can express a sense of probability:

I hear a whistle. That would be the five o'clock train.

Uses of Used to
The auxiliary verb construction used to is used to express an action that took place in the past, perhaps customarily, but now that action no longer customarily takes place:

We used to take long vacation trips with the whole family.

The spelling of this verb is a problem for some people because the "-ed" ending quite naturally disappears in speaking: "We yoostoo take long trips." But it ought not to disappear in writing. There are exceptions, though. When the auxiliary is combined with another auxiliary, did, the past tense is carried by the new auxiliary and the "-ed" ending is dropped. This will often happen in the interrogative:

Didn't you use to go jogging every morning before breakfast?
It didn't use to be that way.

Used to can also be used to convey the sense of being accustomed to or familiar with something:

The tire factory down the road really stinks, but we're used to it by now.
I like these old sneakers; I'm used to them.

Used to is best reserved for colloquial usage; it has no place in formal or academic text.
