Ice in November growing (4)
I believe the answer is:
berg
'ice' is the definition.
(thesaurus)
'in november growing' is the wordplay.
'in' indicates a hidden word.
'BERG' is hidden in the letters of 'november growing'.
(Other definitions for berg that I've seen before include "One who scored" , "Small version of ice mountain" , "Mass of ice floating at sea" , "South African mountain - Austrian composer" , "feature of icy waters" .)
