解答欄

1. Origins, structure, and basic meaning

• Structure: 解答欄 (かいとうらん) is a noun for the field or box provided for writing an answer.
• Basic usage: It appears in instructions to write in an answer field or when a final answer box was left blank.
  • 答えは問題用紙ではなく解答欄に記入してください。 — Write the answer in the answer field, not on the question sheet.
  • 最後の解答欄だけ空白のまま提出してしまった。 — I submitted it with only the final answer box blank.

2. Common pitfalls and similar expressions

• Question sheet and answer field
  • 問題用紙 is the sheet presenting the questions, while 解答欄 is the space for an answer. The writing destination takes に, as in 解答欄に.
