enojar
/enoˈxaɾ/ · A2 · verb
to become angry
😡 en + enojo: to put into annoyance; cousin of English annoy
Enojar and English annoy both come from Late Latin inodiare, built on in odio = in hatred. So enojar is literally to put someone in odium. Add -se (enojarse) and the anger turns on yourself: to get angry.
