IPA: /ɪˈnɒkjuəs/
KK: /ɪˈnɑkjuəs/
Something that is harmless and does not cause any injury or offense.
The innocuous comment did not upset anyone in the meeting.
Innocuous → It is formed from "in-" (meaning not) and "nocuus" (from Latin "nocere", meaning to harm). The word "innocuous" means not harmful or not likely to cause injury.
Think of 'not' ('in-') causing 'harm' ('nocere') — that's why innocuous means something that is not harmful.
