An English learning column uses a short rejection-based scenario to teach three usage points: choosing the preposition for day/time phrases (“on Sunday”), using “puncture” figuratively, and applying the idiom “dead on arrival (DOA)” to early failure.

Background and earlier position: “Sunday” vs “on Sunday”

What changed now: describing rejection using “dead on arrival (DOA)” and “puncture”

Why it matters for UPSC preparation

These language points support clearer UPSC Essay writing. Correct preposition use for day/time sentences supports basic grammar accuracy, and idioms like “dead on arrival (DOA)” and “puncture” help describe early rejection and emotional impact in a concise way.
