Feeble type with mischievous child (4)
I believe the answer is:
wimp
'feeble type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'with mischievous child' is the wordplay.
'with' becomes 'w' (abbreviation).
'mischievous child' becomes 'imp' (imp can mean a misbehaving child).
'w'+'imp'='WIMP'
Can you help me to learn more?
(Other definitions for wimp that I've seen before include "Informally, an ineffective man" , "Milksop" , "Drip" , "Wet" , "Informally, an ineffectual man" .)
