品詞

1. Origins, structure, and basic meaning

• Structure: 品詞 (ひんし) is a compound noun for a grammatical class such as noun or verb assigned by syntactic behavior.
• Basic usage: どの品詞になるか考える determines a word’s function in a sentence, while 品詞も辞書の欄に書く makes grammatical class information recorded alongside meaning.

2. Common pitfalls and similar expressions

• Contextual classification and dictionary field
  • 品詞になる asks about function in the sentence, whereas 品詞も書く records the analysis as a field. A word’s meaning is not identical to its part of speech.
