IPA: /prəˈklɪtɪk/
KK: /prəˈklɪtɪk/
Relating to a type of word that is attached to the beginning of another word and forms a single unit with it, often affecting pronunciation or meaning.
In the phrase 'I'm', the 'I' is a proclitic that combines with 'am'.
A type of word that is attached to the start of another word and cannot stand alone by itself.
In the phrase 'I'm going', 'I' is a proclitic that attaches to 'am'.
Proclitic is formed from "pro-" (meaning before) and "clitic" (from Greek "klitikos", meaning to lean). The term refers to a word that leans on the preceding word for its pronunciation, thus appearing before it in speech.
Think of a word that 'leans' ('clitic') on another word that comes 'before' it ('pro-') — that's what a proclitic does.
