IPA: //ʌnˈpoʊɪtɪk//
KK: /ʌnˈpoʊɪtɪk/
Not having the qualities or characteristics of poetry; lacking in beauty or expressiveness.
The speech was so unpoetic that it failed to inspire the audience.
Unpoetic → It is formed from "un-" (meaning not) and "poetic" (from Greek "poetikos", meaning relating to poetry). The word "unpoetic" means not relating to or characteristic of poetry.
Think of 'not' ('un-') being added to something 'relating to poetry' ('poetic') — that's why unpoetic means not poetic.
