ほんすじ (honsuji)

VS
Japanese Option B

骨子

こっし (kosshi)
N1 / CEFR Syllabus

Nuance Contrast & Translation Difference

When translating "main" into Japanese, you must choose carefully between 本筋 and 骨子. In Japanese, 本筋 (ほんすじ (honsuji)) is typically associated with "main plot, main point, main line (of argument/story)" (Syllabus Level: N2) and represents Refers to the central or essential part of a story, argument, or discussion, as opposed to digressions or minor details.. On the other hand, 骨子 (こっし (kosshi)) maps to "main points, gist, outline, backbone, fundamental principles" (Syllabus Level: N1) and represents Refers to the essential core or fundamental structure of an argument, plan, or document. It represents the most important parts without the detailed explanations.. A literal translation of "main" can often sound unnatural to native Japanese speakers if mixed up!
