IPA: /nɒnˈɑːɡjʊmənt/
KK: /nɑnˈɑrgjʊmənt/
Something that is not an argument or does not involve a disagreement or debate.
The discussion was more of a nonargument, as everyone agreed on the topic.
Nonargument → It is formed from "non-" (meaning not) and "argument" (from Latin "argumentum", meaning a reason or evidence). The word "nonargument" refers to something that is not a reason or evidence, indicating a lack of argumentation.
Think of 'non-' meaning 'not' and 'argument' referring to a reason or evidence — so a nonargument is something that is not a reason.
