almond

English almond comes from Middle English almond, almaund, from Old French almande, amande, from Vulgar Latin *amendla, *amandula, itself from Latin amygdala, borrowed from Ancient Greek ἀμυγδάλη (amugdálē), whose own origin is uncertain.

The word's form was reshaped along the way by association with the Latin name Amandus, and by the many European words borrowed from Arabic that begin with the article al-, even though almond itself didn't come from Arabic.

It's a doublet of amygdala and amygdale (the brain structure, named for its almond-like shape) and of mandorla, the almond-shaped halo in religious art.
