IPA: /ɪkˈstreɪniəsnəs/
KK: /ɛkˈstreɪniəsnəs/
The condition of being unnecessary or not relevant to a particular situation or subject.
The extraneousness of the details made it hard to focus on the main point of the discussion.
Extraneousness → It is formed from "extra-" (meaning outside) and "aneus" (from Latin *aneus*, meaning pertaining to or related to) combined with the suffix "-ness" (meaning the state or quality of). The word describes the state of being outside or not essential to the matter at hand.
Think of 'extra' meaning something 'outside' or 'beyond' and 'ness' indicating a state — so extraneousness refers to the quality of being outside or irrelevant to the main topic.
