Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between 安心する and 思い込む.
In Japanese, 安心する (あんしんする (anshin suru)) is typically associated with "to be relieved, to feel at ease" (Syllabus Level: N4) and represents する verb. Used to express a feeling of relief or peace of mind after a period of worry or anxiety. Opposite of 心配する.
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!
