Under control around cold ski slope? (7)
I believe the answer is:
incline
'ski slope?' is the definition.
'incline' can be an answer for 'slope?' (synonyms). I'm not certain of the 'ski' bit.
'under control around cold' is the wordplay.
'under control' becomes 'inline' (as in keeping someone in line).
'around' is an insertion indicator.
'cold' becomes 'c' (eg on taps).
'inline' going around 'c' is 'INCLINE'.
Can you help me to learn more?
(Other definitions for incline that I've seen before include "Have a tendency to do or be something" , "Have tendency or slope" , "bow" , "Gradient" , "Bend forwards" .)
