IPA: /ˌkætəˈlɛksɪs/
KK: /kætəˈlɛksɪs/
The missing of one or more syllables at the end of a line in poetry, particularly in the last part of the line.
The poet used catalexis to create a unique rhythm in his verses.
Catalexis is formed from "cata-" (from Greek "kata", meaning down or against) and "lexis" (from Greek "lexis", meaning word or speech). The term refers to a condition in poetry where a line is incomplete or cut off, thus relating to the idea of something being 'down' or 'against' the full expression of words.
Think of 'cata-' meaning 'down' and 'lexis' meaning 'word' — this helps you remember that catalexis refers to a line of poetry that is 'cut off' or incomplete.
