List of acronyms and initialisms
This list contains acronyms, initialisms, and pseudo-blends.
For the purposes of this list:
- acronym = an abbreviation pronounced as a series of constituent letters
- initialism = an abbreviation pronounced wholly or partly using the names of its constituent letters
- pseudo-blend = an abbreviation whose extra or omitted letters means that it cannot stand as a true acronym, initialism, or portmanteau (a word formed by combining two or more words).
- (a) = acronym in the example: SARS – (a) Severe acute respiratory syndrome
- (i) = initialism in the example: CD – (i) Compact disc
- (p) = pseudo-blend in the example: UNIFEM – (p) United Nations Development Fund for Women
- (s) = symbol (none of the above, representing and pronounced as something else; for example: MHz – Megahertz)
Add new entries here or in the sub-pages
Because of the list's size, acronyms and initialisms beginning with certain characters appear in separate articles.
Please add your own entries, in this page or in the appropriate sub-page. Use a quasi-dictionary order, with lowercase treated the same as uppercase and ignoring non-alphanumeric characters (hyphens and such). This means that only alphanumeric characters have any significance in determining order, and that lowercase letters occupy the same ordering position as uppercase (in tie-breaker cases, list lower case first). For example: Algol appears before ALS. (This differs from a strict ASCII ordering)
