弾
たま · tama · JLPT N3 · noun
bullet
🏹 弾 = 弓 bow + 単 single: one pellet launched from a bow
The 弓 bow radical sits on the left, and 単 (single) on the right gives the sound. It first meant a pellet bow, then the pellet itself, and now any bullet or shot. As a verb it is 弾く (hiku), to pluck a string like a bowstring.
