Nuance Contrast & Translation Difference

When translating "sincerity" into Japanese, you must choose carefully between 誠意 and 真心. In Japanese, 誠意 (せいい (seii)) is typically associated with "sincerity; good faith; honest intention" (Syllabus Level: N3) and represents Refers to sincerity, good faith, or honest intentions. Often used as 誠意を見せる. On the other hand, 真心 (まごころ (magokoro)) maps to "sincerity; devotion; pure heart; honest love; whole heart" (Syllabus Level: N3) and represents Refers to deep sincerity, devotion, a pure heart, or honest love shown toward others. A literal translation of "sincerity" can often sound unnatural to native Japanese speakers if mixed up!
