The art of being technically correct about something nobody asked.
means A fact, detail, or concern so minor it carries no real weight or consequence.
from From Latin 'trivialis,' meaning 'found anywhere' or 'commonplace' — rooted in 'trivium,' the place where three roads (tri- 'three' + via 'road') meet. A trivium was a literal crossroads, the kind of public spot where anyone might loiter and gossip, so 'trivial' came to mean the sort of ordinary chatter you'd hear there — common, unremarkable, beneath serious notice.
