Suitable to be eaten; edible.
From Old French 'comestible', derived from Latin 'comestus' (eaten), past participle of 'comedere' (to eat up), from 'com-' (together) and 'edere' (to eat). The word entered English in the 16th century.
The root 'edere' (to eat) is the same Latin word hiding inside 'edible,' but 'comestible' sounds fancier because it came through French courtly language—showing how the same concept gets dressed differently depending on its social journey.
