Abbreviations
What is an abbreviation?
An
abbreviation is a shortened form of a word or phrase used mainly in writing to
represent the complete form.
Why we use abbreviations:
When and how to use
abbreviations:
*There is no
clear rule about when to use a period with abbreviations (U.S.A. or USA). The best idea is to just stay consistent
throughout your entire paper. If you
use periods for one abbreviated word, do so for all the other abbreviated
words.
·
Abbreviations for Academic Degrees and
Titles:
Use
abbreviations for academic degrees and for the following common titles when
used with a person’s name:
Mr., Mrs., Ms.,
Dr., Jr., and Sr..
Other
titles, such as governor, colonel, professor, and reverend, are spelled out.
Example: The doctor asked Ms. Huss, Professor James,
and Colonel Smith to present the portrait of St. Thomas to Judge Wilson on the
occasion of her receiving a Ph.D. in religious studies.
Use abbreviations for agencies, groups, people,
places, or objects that are commonly know by capitalized initials.
FBI
UCLA DNA molecules CD-ROM
If you wish to use a specialized abbreviation that
may be unclear to your audience, write out the term in full the first time it
occurs and place in parentheses the abbreviation that you will use from then
on.
Example: The Modern Language Association
(MLA) recently issued new guidelines for citing electronic sources.
This example indicates that the writer will
from then on use the abbreviation MLA.
· Abbreviations for Terms Used with Numbers:
Use abbreviations for terms commonly used with numbers, especially times,
dates, amounts, and other units of measure.
Examples:
1000C.E. $16.29
500B.C. No.12 in a series
3:30P.M.
Note that you should use
abbreviations for units of measure only when they appear with numbers; never use
abbreviations by themselves.
Wrong: Jane will meet Todd sometime in the A.M.
Correct: Jane will meet Todd sometime in the morning.
· Abbreviations for Common Latin Terms:
Use abbreviations for common Latin
terms used in footnotes, bibliographies, or parenthetical comments. In the main text, spell out the English
equivalents.
Examples:
e.g. for example
i.e. that is
c.f. compare
This rule applies also to etc. (et
cetera, meaning ‘and so fourth”). Avoid
using etc. in formal writing. Instead,
use the English and so forth or and soon.
Never write and etc., because
et is Latin for ‘and.”
Weak: During my year in Paris I went to
concerts, festivals, movies, etc.
Revised: During my year in Paris I saw many cultural events,
including five rock concerts, three festivals, and ten foreign films.
· Plurals of Abbreviations:
Do not use an apostrophe when forming
the plural of an abbreviation.
Faulty: I have misplaced three of my
CD’s.
Revised: I have misplaced three of my
CDs.
By now we are sure that you have
encountered with a few troubleshoot questions about abbreviations. As a matter of fact, this topic has many
specific and detailed misconceptions, but here is a list that hopefully will
help you out during those sticky times.
· Acronyms vs. Abbreviations:
Although they look familiar, acronyms and
abbreviations are different. Taking the first initials of a phrase or
compounded-word and using those initials to form a word that stands for
something is known as an acronym.
How to know which one is which?
By the pronunciation of the word. If you read the
word letter-by-letter, then it’s an abbreviation. If you read the word
fluently, then it’s an acronym. Examples
of acronyms: NATO, AIDS, LASER
Examples of
abbreviations: FBI and HIV
How to know
when to use them with articles?
One of the most often asked questions about grammar
has to do with the choice of articles (a,
an, the) to precede an abbreviation or acronym. Again, it depends on how
you say the word. Lets try the following examples: do we say an FBI agent or a FBI agent? The answer is an
FBI agent because we pronounce the word with an “eff-sound." We see a UFO, because although it begins with a
“U”, we pronounce the “U” as if it were spelled “yoo.”
· Units of measure:
Generally, you would use these
only in technical writing. Nevertheless, always leave a space between the
number and the abbreviation, and do not put an s after such abbreviation even when the plural is indicated. Also,
do not put a period with such abbreviations except for in. (inches) because it
might be confused with the preposition in.
Examples: 15 kg, 4 in., 2 lb
When the term of measurement is used as a modifier,
put a hyphen between the number and the abbreviation.
Examples: a 15-ft board, a 5-lb line.
· Long, common phrases:
Abbreviations such as IQ (Intelligence Quotient),
rpm (revolutions per minute), mph (miles per hour) and mpg (miles per gallon) are
acceptable even in formal academic text and may be used without periods. It
depends on the writer’s style.
· Place and time:
For time:
either lower or upper case can be used with A.M., a.m., P.M., p.m.
For place in time: use B.C. (before Christ) after the date, and
A.C. (after Christ) before the date.
For both cases, many stylebooks
recommend SMALL CAPS for all appearances because this effect allows the
abbreviation to blend smoothly with the rest of the text. As for the periods,
there is no clear rule about when to use them, so it’s all up to the writer.
Note: it is considered bad form to use these abbreviations without
a specific number attached to them: “We will do the assignment in the a.m.”
· Common Latin terms:
For these abbreviations, such as i.e. (that is),
e.g. (for example), etc. (and so forth), and et ali (and others), you do not
italicize or underline them. The most common mistake is when the abbreviation
i.e. (that is) is mistaken with other abbreviations. The i.e. is generally used
to introduce matter that is explanatory as opposed to being the name of an
example of list of examples.
How to know when to use it?
If you can say “for example” as a substitute for the
abbreviation, you want to use e.g., and not i.e.
·
Plurals in abbreviations:
Another common mistake is that very often a writer
uses an apostrophe after the abbreviation. This is not allowed; so don’t put an
apostrophe after an abbreviation, no matter how plural it is.
Faulty:
All the laser’s pointed out to the tree.
Revised:
All the lasers pointed out to the tree.
