part of the brain, from Latin amygdalum "almond" (which the brain parts resemble), from Greek amygdale "almond" (see almond). English also had amygdales "the tonsils" (early 15c.), from a secondary sense of the Latin word in Medieval Latin, a translation of Arabic al-lauzatani "the two tonsils," literally "the two almonds," so called by Arabic physicians for fancied resemblance.
