Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between いる and 思い込む.
In Japanese, いる (いる (iru)) is typically associated with "to be, to exist (animate objects)" (Syllabus Level: N4) and represents 人間や動物など、動くものの存在を表します。物や植物には「ある」を使います。
Expresses the existence of animate objects.
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!
