Quiet and poorly? This may help (4)
I believe the answer is:
pill
'this may help' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'quiet and poorly?' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'and' is a charade indicator (letters next to each other).
'poorly?' becomes 'ill' ('ill' can be similar in meaning to 'poorly').
'p'+'ill'='PILL'
Can you help me to learn more?
(Other definitions for pill that I've seen before include "nuisance to put up with" , "Dose of medicine" , "Pellet of medicine" , "Lozenge" , "Medical tablet" .)
