año
/ˈaɲo/ · A1 · noun · m
year
📅 From Latin annus (year) — same root as annual; Latin nn became Spanish ñ
Latin double n regularly turned into ñ in Spanish, so annus became año. English kept the root in annual and anniversary. Age uses the same word: tener 20 años = to have 20 years. Keep the ñ — ano without it means anus.
