irrelevante
/ireleˈbante/ · B2 · adj
irrelevant, unimportant, moot
🗑️ ir- (not) + relevante (relevant, from Latin relevare, to lift up) = not worth raising
Ir- is the negative prefix, a form of in- before r. Relevante comes from Latin relevare, to raise up. So irrelevante is something not worth lifting into the discussion, which makes it unimportant or moot.
