Limp young creature turning on policemen (7)
I believe the answer is:
flaccid
'limp' is the definition.
(synonyms)
'young creature turning on policemen' is the wordplay.
'young creature' becomes 'calf' (calf is a kind of animal. I am not sure about the 'young' bit.).
'turning' shows that the letters should be reversed in order.
'on' says to put letters next to each other.
'policemen' becomes 'CID' (abbreviation for Criminal Investigation Department).
'calf' written backwards gives 'flac'.
'flac'+'cid'='FLACCID'
Can you help me to learn more?
(Other definitions for flaccid that I've seen before include "Limp, flabby" , "Floppy" , "Lax" , "Limp and soft" , "Droopy" .)
