Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between 欠席する and 思い込む.
In Japanese, 欠席する (けっせきする (kesseki suru)) is typically associated with "to be absent (from a meeting, class, etc.)" (Syllabus Level: N4) and represents 「出席する」の反対の意味で、会議や授業、イベントなどに「いない」ことを指します。これもフォーマルな場面で使われます。The opposite of "出席する," meaning to be absent from a meeting, class, or event. Also used in formal contexts..
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!
