Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between 失望する and 思い込む.
In Japanese, 失望する (しつぼうする (shitsubō suru)) is typically associated with "to be disappointed; to lose hope" (Syllabus Level: N3) and represents 「失望する」は、期待していたことが叶わず、がっかりする気持ちを表します。人や結果に対して使われることが多いです。.
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!
