late 14c., "roof of the mouth," from Old French palat and directly from Latin palatum "roof of the mouth," perhaps of Etruscan origin [Klein]. Popularly considered the seat of taste, hence transferred meaning "sense of taste" (late 14c.), which also was in classical Latin. Related: Palatal; palatalize.
palate pal·ate (pāl'ĭt)
n.
The bony and muscular partition between the oral and nasal cavities; the roof of the mouth.
The roof of the mouth. The palate separates the mouth from the nasal cavity.
Note: It is sometimes said that a person has a “cultivated palate” if he or she has a discerning taste for food.
