Phrase. July 24, 2015, Word of the Day
Catch-all phrase implying a polite, persistent request or order (depending on context) to "do what is required". The issue is that what is required or "needful" is usually left unspecified or vaguely specified at best.
"Dear Sir, I observed that there were a lot of dogs pissing in the garbage at the blocked traffic light. Kindly do the needful."
