Nuance Contrast & Translation Difference

When translating "be" into Japanese, you must choose carefully between 役に立つ and 遅刻する. In Japanese, 役に立つ (やくにたつ (yaku ni tatsu)) is typically associated with "to be useful, to be helpful" (Syllabus Level: N4) and represents A set phrase meaning to be useful or helpful for someone or something. It describes the utility of an object, skill, or person. Often followed by the particle に. On the other hand, 遅刻する (ちこくする (chikoku suru)) maps to "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.. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
