👁️ ojo = two round o's with a j nose between: the word is a face with eyes
From Latin oculus (eye), same root as ocular and oculist. The spelling itself is the hook: o-j-o is two eyes around a nose. Spaniards say ¡Ojo! to mean watch out, literally eye!, so one word covers the organ and the warning.
