Pleasant, agreeable, or attractive (archaic term rarely used in modern English).
From Old French 'amene,' derived from Latin 'amoenus' meaning pleasant. The word faded from common use as English developed synonyms like 'pleasant' and 'agreeable.'
Medieval poets loved calling castles and gardens 'amene,' but the word basically disappeared because 'pleasant' does the same job in three fewer syllables—language naturally kills off the inefficient words.
