Nuance Contrast & Translation Difference

When translating "be" into Japanese, you must choose carefully between 安心する and いる. 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, いる (いる (iru)) maps to "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. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
