List of acronyms and initialisms: R
This list contains acronyms, initialisms, and pseudo-blends that begin with the letter R.
For the purposes of this list:
- acronym = an abbreviation pronounced as a series of constituent letters, e.g., SARS = severe acute respiratory syndrome
- initialism = an abbreviation pronounced wholly or partly using the names of its constituent letters, e.g., CD = compact disc
- 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)
