morsel: [13] Etymologically, a morsel is a piece ‘bitten’ off. The word comes from Old French morsel, a diminutive of mors ‘bite’. This in turn goes back to Latin morsus, a derivative of the same base as the verb mordēre ‘bite’. Other English words from the same source include mordant [15] and remorse. => mordant, remorse[morsel etymology, morsel origin, 英语词源]
