Nuance Contrast & Translation Difference

When translating "be" into Japanese, you must choose carefully between 遅刻する and 思い込む. In Japanese, 遅刻する (ちこくする (chikoku suru)) is typically associated with "to be late, to come late" (Syllabus Level: N4) and represents A verb used when someone arrives later than the scheduled time for an appointment, class, work, etc. It implies missing the start time.. 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!
