挠 (náo): เพื่อรอยขีดข่วน

The mosquito bites made my arm itch unbearably, and I couldn't help scratching constantly.

The kitten scratched the sofa with its claws, leaving several scratch marks.

When he thinks about a problem, he always likes to scratch his head, as if that could help him come up with an answer.

When my back itches, I can't scratch it myself, so I have to ask a family member for help.
