Morphology

amygdaloidal = amygdala (semi-transparent) = amygdal + oidal

The connection to 'amygdala' is clear, but the specific meaning of resembling an almond in form is not immediately obvious to all learners.

Etymology

The word amygdaloidal comes from the old Greek root amygdalē, which means 'almond'. So amygdaloidal means 'almond-shaped', and we use it for things like small cavities or crystals in rocks that look like a little almond.
