comprobar
/kompɾoˈbaɾ/ · A2 · verb
to check, to check on, to check out, to see, to check to see
✅🔍 com + probar: to prove thoroughly, so to check or verify
From Latin comprobare: com- (fully) + probare (to test, prove). English probe, proof and approve share the root. Probar alone means to try or test; adding com- makes it to confirm that something holds true.
