Etymology: The brain's amygdalae take their name from the almond. The Ancient Greek "amugdalē" meant "almond," and the structures were named for their resemblance to that nut's shape. The same Greek root gave English "almond" (through a different route), so the two words are doublets, each arriving by its own path from one ancestor. The Greek word passed into Latin as "amygdala," meaning both "almond" and, in anatomical use, the structure itself. The plural "amygdalae" is the standard Latin-style form, which is why it is used alongside the English plural "amygdalas." It is a learned borrowing, so the word reached English through scholarly Latin rather than everyday speech.
