原作

• 読み: げんさく
• ローマ字: gensaku
• 漢字の分解: 原 (original/source) + 作 (work/creation) → original work/source material
• 発音: /ɡeɴ.sa.kɯ/

意味

The original source material — the manga, light novel, game, or other work that an anime or adaptation is based on.

原作 is essential vocabulary for discussing adaptations. Fans frequently compare anime to their 原作, debating whether the adaptation did the source material justice. '原作勢' (gensaku-zei) refers to fans who read the original before the adaptation. The term is central to discussions about pacing, cut content, and faithfulness.

例文

1. 原作読んでからアニメ見るとカットされたシーン多くて悲しい。
2. 原作の方が面白いって言う人多いけど、アニメも良くない？
3. 原作勢としてはこの展開知ってたけど黙ってた。
