An olive, the small dark or green fruit from an olive tree that is eaten or pressed to make oil.
Derived from Arabic 'az-zaytūnah' (the olive), related to 'aceite' through the same Semitic root. The diminutive or modified form evolved as the fruit name while 'aceite' became the oil name.
The fact that Spanish has two words from the same Arabic root—one for the fruit (aceituna) and one for the oil (aceite)—shows how languages evolved different terms for related things that were economically important to Mediterranean civilizations.
