An initialism is an abbreviation formed from the initial letters of a multi-word name or phrase, pronounced by articulating each constituent letter individually rather than as a single word. Parameters: (1) the source must be a multi-word expression; (2) the abbreviation comprises one letter (or occasionally a letter group) from each word; (3) pronunciation is letter-by-letter, distinguishing it from an acronym which is spoken as a word. The persistence mechanism is language convention: repeated usage in writing and speech entrenches the form across speakers and generations.

Definition
Why it is in scope
An initialism is a human-made linguistic construct: a type of abbreviation formed from the initial letters of a multi-word name or phrase, pronounced by articulating each letter individually rather than as a word. It is built to persist through language conventions, teaching, and repeated usage in both writing and speech.

An initialism is a specific kind of abbreviation. The competent-speaker test: a speaker familiar with abbreviations would say 'an initialism is a type of abbreviation.' The note pins the sense of 'initialism' as the abbreviation type pronounced letter-by-letter (e.g., FBI, NATO), as distinguished from acronyms pronounced as words (e.g., NASA). Both are instances of the broader class 'abbreviation.'

An initialism is maintained for the sake of communication — it compresses multi-word phrases into pronounceable forms (NASA, ATM) for efficient discourse. Law 8d: the linguistic construct serves communication.
