inmenso
/imˈmenso/ · B2 · adj
giant, huge
🐋 in + menso = un-measured, from Latin immensus: too big to measure
Latin immensus is in- (not) + mensus (measured), from metiri, to measure, the same root as English measure. Something inmenso can't be measured. English has the same word, immense, so it is an easy cognate.
