Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between 役に立つ and 込み合う.
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, 込み合う (こみあう (komiau)) maps to "to be crowded, to be packed" (Syllabus Level: N3) and represents 場所が多くの人や物でいっぱいになり、混雑している状態を表す動詞。A verb describing a place filled with many people or things, making it crowded.. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
