excavar
/eɡskaˈbaɾ/ · B2 · verb
to excavate, dig
⛏️🕳️ excavar = ex- (out) + cavar (dig) → dig something out
Spanish excavar comes from Latin excavare: ex- means out and cavus means hollow. Cavar (to dig) is the same family as English cavity and cave. English excavate is the near twin, so the link is direct.
