鼻血

1. Origins, structure, and basic meaning

• Structure: 鼻血 is read as はなぢ and means “nosebleed”.
• Basic usage: It covers pretending to have a nosebleed in a play and stepping away after an actual one during practice.

2. Common pitfalls and similar expressions

• 鼻血が出る / 鼻血を出す
  • 鼻血が出る presents the nosebleed as the thing that occurs. 鼻血を出す can also mean that a person has a nosebleed; it does not inherently mean causing one intentionally.
