noun
Rare term for a written annotation or explanatory note, similar to 注釈 (ちゅうしゃく) but less common.
古文書の注文を読むのは難しい。
Reading the annotations in old documents is difficult.
注釈 is the common word for annotation or commentary; 注文 is a rare synonym.
Composed of 注 (annotation, note) and 文 (writing, sentence). The exact historical derivation is uncertain, but the spelling is conventionally associated with the meaning of an explanatory note.
