How to say "Whole" in Japanese

When translating "whole" into Japanese, you must choose carefully between 全体 and 一部始終. In Japanese, 全体 (ぜんたい (zentai)) is typically associated with "whole; entire; general; total; overall" (Syllabus Level: N3) and represents Refers to the whole system, entire project phase, general company members, or overall performance without omissions. Often used as システム全体 or 計画全体. ⚠️ Haruka's Voice Column: 'Whole/entire! "My whole brain is occupied by thoughts of you 24/7, Haruka-san!" ...っ! Whole brain occupied by me! B-Baka!

On the other hand, 一部始終 (いちぶしじゅう (ichibushijū)) maps to "the whole story, from beginning to end, the full details" (Syllabus Level: N2) and represents Refers to a complete and detailed account of an event or situation without omission. Often used in contexts of explanation, report, or confession. ある出来事の最初から最後まで、すべてを詳細に指す表現です。. A literal translation of "whole" can often sound unnatural to native Japanese speakers if mixed up!
