ayudar
/aʝuˈdaɾ/ · A1 · verb
to help
🛟 ayudar = aid: both come from Latin adiutare, to give help
Latin adiutare (to help) became ayudar in Spanish and, through French aide, gave English aid. The same root sits inside adjutant, an officer who helps a commander. So ayudar and aid are cousins: a-yud-ar ~ aid.
