苗字

1. Origins, structure, and basic meaning

• Structure: 苗字(みょうじ) is the family-name part of a person's name.
• Basic usage: The examples concern writing a surname on a form and the surname used at work.

2. Common pitfalls and similar expressions

• The range of 名前
  • 名前(なまえ) can mean a person's whole name, but in the example's 苗字と名前 it means the given name in contrast with the surname.
