常見錯誤

❌I fell and hurt my buttock.
✅I fell and hurt my buttock / my buttocks.
💡Both are correct: singular focuses on one side, plural on the whole area.
❌She has a pain in her buttock cheek.
✅She has a pain in her buttock.
💡'Buttock cheek' is redundant; 'buttock' already refers to one of the two sides.
