Abbrevations
First, a quick definition of terms.
An abbreviation is a shortened form of a name
or term (e.g., postop for postoperative,
kg for kilogram).
An acronym is an abbreviation formed from
the initial letters of a term (e.g., FBI for Federal
Bureau of Investigation).
All acronyms are abbreviations, but not all
abbreviations are acronyms.
Since the mid-20th century, acronyms have
generally formed pronounceable words
(e.g., laser, from light amplification by
stimulated emission of radiation);
however, the rage for acronyms has
outstripped the bounds of pronunciation, and
this is no longer a requirement
List of Terminology: ABBREVIATIONS page
Margins- 2.5 cm all sides
Font- Times New Roman 12 pt
Alignment - text flush left, page
numbers flush right
Page Title
 Type “LIST OF ABBREVIATIONS” in ALL CAPITAL
LETTERS
 This should be typed 2 line spaces from the top
margin, and centered within the left and right
margins.
Text start next 2 line spaces after the page title;
double-spaced
Alignment
Abbreviated forms are flush left
 The first letter of every extended form (the full
wording) must be in line with one another.
The best way to do this is setting a “left tab”.
 AVOID using the space bar because unevenness
usually results.
Spacing
Each entry should be single-spaced,
double space between entries.
 For example, the explanation of
“UNESCO” extends beyond one line and
has two lines single-spaced.
 However, the space between UNESCO
and PV, and the space between UNESCO
and WHC are double-spaced.
Such spacing facilitates reading.
Case
use title case or standard capitalization
style for proper nouns, whichever is more
appropriate.
Page Number
roman number, lowercase: “x” or the
number that follows the last page of the
immediately preceding List of Figures.
•Include the heading “LIST OF ABBREVIATIONS” in all capital
letters, and center it 1″ below the top of the page.
•Include one double-spaced line between the heading and the
first entry.
•Arrange your abbreviations alphabetically.
•Abbreviations must align with the document's left margin or be
indented to the right of the left page margin using consistent
tabs.
•If an entry takes up more than one line, single-space between
the two lines.
•Include one double-spaced line between each entry.
•The List of Abbreviations page(s) must be numbered with
consecutive lower case Roman numerals centered with a 1/2″
margin from the bottom edge.
Abbreviations
Make sure our abbreviation list is in
alphabetical order and that
abbreviations starting with a number
are included at the top of the list
before those abbreviations starting
with the letter “A”.
A list of abbreviations is usually
optional, but of great help to the
reader.
It contains all the significant
abbreviations used in our thesis.
List of abbreviations in the thesis
.
When do we use a list of abbreviations
If we use a lot of technical abbreviations in our thesis, then it is
advisable to provide a list of abbreviations.
Not every reader of our thesis will be familiar with those
abbreviations, and many will find them difficult.
The readability of our document is improved with a list of
abbreviations.
Where do you put the list of
abbreviations in your thesis?
Place the list of abbreviations at the
beginning of the document, just after
the table of contents.
 The readers of our thesis can then
find any abbreviations unknown to
them in this specific place.
You add the list of abbreviations
header to your table of contents, so
that is it clear to the reader that an
explanation of abbreviations has been
added to your thesis.
Example: list of abbreviations
It may be that we only
have a few abbreviations
that require explanation.
You can provide these
explanations in a footnote.
Then the reader doesn’t
have to pause to backtrack
for those few
abbreviations.
Example: Write the abbreviation in full at first mention
In this study, the Customer Relationship Management (CRM) at Vroom &
Dreesman (V&D) is examined. At V&D, CRM has been used for many years to
ensure that the focus is on customer contact and that this contact is
increasingly improved.
Using abbreviations (acronyms) in your text
There are many rules with regard to using abbreviations in a
thesis.
 In short, when we use an abbreviation, or more specifically
an acronym, in our thesis for a particular word or phrase, we
write the first occurrence of the word or phrase in full.
Immediately thereafter, you place in parentheses the
abbreviation that we will use in the rest of the document.
Additional lists in your thesis
In addition to the list of abbreviations, you can also use a list
of tables and figures and a glossary.
When doing so, make use of the following order
The following table describes
the significance of various
abbreviations and acronyms
used throughout the thesis.
The page on which each one
is defined or first used is also
given.
Nonstandard acronyms that
are used in some places to
abbreviate the names of
certain white matter
structures are not in this list.
When to Abbreviate
Always use abbreviations for units of
measurement that are accompanied by numeric
values (except day, week, month, year).
Saving space is not a sufficient reason to
abbreviate; the abbreviation must also help the
reader to comprehend our point.
Here are some questions that can help us decide
whether a particular term should be abbreviated
in our writing.
Does using the abbreviation provide
an advantage over not using it?
Abbreviating lengthy or complex,
frequently repeated terms can speed
reading comprehension.
For example, a review of a test
instrument (e.g., the Wechsler Adult
Intelligence Scale) might involve numerous
references to the name; using its
abbreviation (WAIS) would be likely to help
the reader.
However, a multitude of unfamiliar abbreviations can reduce
rather than enhance the clarity of our writing.
In general, it’s best to limit the use of abbreviations to cases where
the abbreviation is familiar to the reader and saves space and time
•How many times does the term appear?
•a term should not be abbreviated unless it appears three or more
times after its first mention in a paper (APA Publication Manual, 4.22,
p. 107);
• once a term is abbreviated, the abbreviation must be used
consistently thereafter.
• Note also that there is no rule requiring you to abbreviate a term that
appears three or more times.
•First use: (American Psychological Association [APA], 2009) or American
Psychological Association (APA; 2009)
•Subsequent use: (APA, 2009)
The corresponding reference list entry should contain the author’s full name,
not the abbreviation.
•Correct: American Psychological Association. (2009).
•Incorrect: American Psychological Association (APA). (2009).
•Incorrect: APA. 2009.
Avoid the use of abbreviations in the title of your paper.
It’s fine to use them in headings if they’ve already been introduced, but
don’t introduce them for the first time there.
In general, abbreviations should also be avoided at the beginning of a
sentence, unless this would produce an awkward construction
How do I introduce an abbreviation in the
text?
The first time you use an abbreviation in the text, present both the
spelled-out version and the short form.
When the spelled-out version first appears in the narrative of the
sentence, put the abbreviation in parentheses after it:
•Example: We studied attention-deficit/hyperactivity disorder (ADHD)
in children.
When the spelled-out version first appears in parentheses, put the
abbreviation in brackets after it.
Correct reference entry:
American Psychological
Association. (2011). Dollars
and sense: Talking to your
children about the
economy. Retrieved from
http://www.apa.org/topics/lear
ning/enhance-memory.aspx
Incorrect reference entry:
American Psychological
Association (APA).
(2011). Dollars and sense: Talking
to your children about the
economy. Retrieved from
http://www.apa.org/topics/learning
/enhance-memory.aspx
In the reference list entry, do not include the
abbreviation for the group author.
 Instead, spell out the full name of the group
Can I use abbreviations in the
abstract?
In general, it is not necessary to use
abbreviations in the abstract because the
abstract is so short.
However, if the abbreviation would help the
reader recognize a term or find your article via
search, then it is permissible to include an
abbreviation in the abstract, even if it is not used
three times.
 When you use an abbreviation in both the
abstract and the text, define it in both places
upon first use.
Can I use abbreviations in headings?
 We should avoid them—for example, the reader may skim the
paper before reading it in full, and abbreviations in headings may be
difficult to understand out of context.
So, if a term you intend to abbreviate appears in a heading (e.g.,
the name of a test or measure), spell out the term in the heading
and then when it first appears in the text, spell it out again and
define it there.
Can I use abbreviations in tables and figures?
Yes, you can use abbreviations in tables and figures.
All abbreviations used in tables and figures should be defined in the
table note or figure caption, respectively, even though the
abbreviations will be also be defined in the text if they are used
there.
The purpose of defining abbreviations in the table note or figure
caption is that if other authors reuse your graphical display in a
future paper, the definitions of the terms will be attached.
Additionally, many readers will skim an article before reading it
closely, and defining abbreviations in tables and figures will allow
the readers to understand the abbreviations immediately.
Do all abbreviations
needs to be defined?
Not all abbreviations need to be
defined.
 Consult Merriam-Webster’s
Dictionary to determine what to do:
If the abbreviation has the
designation abbr. after it in the dictionary,
that means it needs to be defined;
•if it does not have this designation, the abbreviation is considered a
word on its own and can be used straight off , without definition.
•You also do not need to define abbreviations for units of measurement
(e.g., cm for centimeters, hr for hour).
Examples of abbreviations that are considered words: IQ, REM, HIV,
AIDS
How do I use the words a and an before
abbreviations?
Use the article that matches the way the abbreviation is pronounced—
an before a vowel sound and a before a consonant sound.
Some abbreviations are pronounced as words (e.g., RAM), and some
abbreviations are pronounced letter-by-letter, which is also called
an initialism (e.g. IQ).
•Examples: an FBI agent, a DSM-5 disorder, a U.S. citizen, an IQ score
How do I make an abbreviation plural?
To make an abbreviation plural, add an –s (or –es, for abbreviations
ending in s already).
Do not add an apostrophe.
•Examples: IQs, RTs, CSes.
Five Ways to Fail When Using
Abbreviations and How to Avoid Them
Define the Abbreviation the First Time You Use It
Define the Abbreviation Once
 Refer to the Abbreviation Consistently
Just Use One Definition for Each Abbreviation
Remember to Use the Abbreviation After Defining It
The proportion of documents with consistent use of abbreviations
falls with larger documents.

Editor's Notes

  • #3: writing of a dissertation or article seems to be the sum of small choices about grammar, syntax, and formatting: Commas or semicolons?  Numbers or numerals? Abbreviations or spelled-out terms? In this post we’ll look at the last of these issues: when and how to abbreviate terms in your academic writing.
