pomegranate: [14] The pomegranate is etymologically the ‘many-seeded apple’. The word’s ultimate ancestor was Latin mālum grānātum (mālum gave English malic ‘of apples’ [18], and grānātus was derived from grānum ‘seed’, source of English grain). In Vulgar Latin this became reduced to simply *grānāta, which passed into Old French as grenate (source of English grenade, so named because early grenades looked like pomegranates).

Before long pome ‘apple’ was added to the term, giving pome grenate – whence English pomegranate. Pome came from Latin pōmum ‘apple, fruit’, which also gave English pomade [16] (an ointment so called because the original version was apple-scented), pomander [15] (etymologically an ‘apple of amber’), pommel [14] (etymologically a ‘little fruit’), and pomology [19].
