abbreviation from initial letters
A short form made from the first letters of the words in a name or phrase, used instead of the full words.
Usage pattern:
an acronym for [full name/phrase]
Common mistake:
Learners often think "acronym" means any short form. In everyday English this is usually accepted, but in careful or technical writing some people use "acronym" only for forms that are pronounced as a word (like "NATO") and prefer "initialism" for forms read letter by letter (like "FBI"). Learners may also forget to say what an acronym "stands for" when explaining it.
Synonyms
abbreviation (More general; includes short forms that are not made from initial letters, while "acronym" usually refers to initial-letter abbreviations.)
Antonyms
full form (Refers to the complete, written-out version of a name or phrase instead of its shortened acronym.)

abbreviation said as a word
In careful language use, a short form made from first letters that you say as one word, not as separate letters.
Common mistake:
Learners often use "acronym" for any group of capital letters, even when each letter is pronounced separately. In technical or linguistic contexts this is seen as a mistake; only forms pronounced as full words (like "NATO") are acronyms, while forms read letter by letter (like "FBI") are called initialisms.
Synonyms
word acronym (Less common descriptive phrase sometimes used to stress that the abbreviation is spoken as a word; emphasizes pronunciation more clearly than "acronym" alone.)
Antonyms
initialism (A related but contrasting term for abbreviations where each letter is pronounced separately, like "FBI".)
