Nuance Contrast & Translation Difference

When translating "be" into Japanese, you must choose carefully between 感動する and 思い込む. In Japanese, 感動する (かんどうする (kandōsuru)) is typically associated with "to be moved, to be impressed, to be touched" (Syllabus Level: N4) and represents Expresses being deeply moved emotionally by something beautiful, powerful, or touching. Often takes 「に. On the other hand, 思い込む (おもいこむ (omoikomu)) maps to "to be under the impression that, to be convinced that, to be deluded into thinking" (Syllabus Level: N3) and represents To firmly believe something, often mistakenly, or to become deeply convinced of a belief. It implies a strong, sometimes incorrect, conviction.. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
