IPA: /ɪˈlɪʒən/
KK: /ɪˈlɪʒən/
The act of leaving out a sound or syllable when speaking, often to make pronunciation easier or to fit a rhythm in poetry.
In poetry, elision helps maintain the meter by omitting certain syllables.
Elision → It is formed from "e-" (a variant of "ex-", meaning out) and "līdere" (from Latin, meaning to strike or cut). The word refers to the act of cutting out or omitting a sound or syllable in speech or writing.
Think of 'cutting out' ('līdere') something 'out' ('e-') — that's why elision means to omit a sound.
