Nuance Contrast & Translation Difference
When translating "be" into Japanese, you must choose carefully between 役に立つ and 延びる.
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, 延びる (のびる (nobiru)) maps to "to be extended; to be postponed; to grow (e.g., hair, height)" (Syllabus Level: N3) and represents Intransitive verb. Can mean 'to be stretched', 'to be prolonged', or 'to grow longer/taller'.. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
