Grammar Notes & Usage Tips

"世話をする" is the full phrase meaning "to look after (someone/something)," so always remember to include the particle を before する.
Use に to show who or what you're looking after — for example, "子どもに世話をする" means "look after the child."
A common mistake is using 世話 alone as a verb — it's actually a noun, so you need to add する to make it an action.
