This list contains acronyms, initialisms, and pseudo-blends that begin with the letter T.
An acronym is an abbreviation pronounced as a series of constituent letters; an initialism is an abbreviation whose pronunciation is wholly or partly the names of constituent letters; and a pseudo-blend is an abbreviation whose extra or omitted letters means that it cannot be considered 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, stands for and is read as something else; for example: MHz - Megahertz)

Please add your own, in 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.)
