世話
せわする · sewasuru · JLPT N4 · noun
looking after
🍼 世話 = world + talk: se-wa, the daily talk of tending to someone
世 (world, se) + 話 (talk, wa) are ateji; the word likely comes from sewashii, busy. Sound hook: say, WAH! — the baby cries and you go look after it. Add する to make the verb: 世話する, to look after.
