Plural of afreet; multiple demons or powerful evil spirits from Arabian and Islamic folklore.
From 'afreet' + '-s' (standard English plural). The Arabic 'ifrit' can take either English '-s' pluralization or be used unchanged, making 'afreets' a fully naturalized English word.
When English adopted 'afreet' from Arabic, it automatically got the '-s' plural treatment, showing how English is eager to make borrowed words look and behave like native words once they become part of the language.
