Go nicely in a curve round a corner (5)
I believe the answer is:
blend
'go nicely' is the definition.
'blend' can be an answer for 'go' ('blend' can be a synonym of 'go'). I am unsure of the 'nicely' bit.
'a curve round a corner' is the wordplay.
'a curve' becomes 'bend' (bend is a kind of curve).
'round' indicates putting letters inside.
'a corner' becomes 'l' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bend' going around 'l' is 'BLEND'.
'in' is the link.
Can you help me to learn more?
(Other definitions for blend that I've seen before include "Combine into one" , "Mix and combine" , "Amalgamate" , "Intermix" , "Combine together" .)
