millet
粟 centers on the grain millet, a small-seeded cereal crop. The meaning is concrete and specific, without broad abstract extensions.
粟 combines 覀 (a variant of 西, possibly suggesting something gathered or covered) with 米 (rice/grain), indicating a type of grain. The exact historical development is uncertain, but the character is consistently associated with millet.
The top 覀 looks like a lid or covering, and the bottom 米 is rice or grain. Picture a covered container of tiny grains: that's millet, a staple grain like rice but smaller.
For ゾク, imagine a flock of birds pecking at millet: the sound 'zoku' mimics the noise of many beaks tapping the grains. Zoku -> ゾク, and the millet feeds the flock.
