Forces getting cold, with zero on loose scree (7)
I believe the answer is:
coerces
'forces' is the definition.
(I know this)
'cold with zero on loose scree' is the wordplay.
'cold' becomes 'c' (eg on taps).
'with' means one lot of letters go next to another.
'zero' becomes 'O' (O resembles 0).
'on' indicates putting letters inside.
'loose' indicates anagramming the letters (letters are loosened from their original positions).
'scree' is an anagram of 'erces'.
'o' going inside 'erces' is 'oerces'.
'c'+'oerces'='COERCES'
'getting' acts as a link.
(Other definitions for coerces that I've seen before include "Forces, pressures" , "Persuades by force" .)
