Partners in prison having no right to cheer (7)
I believe the answer is:
console
'cheer' is the definition.
(consoling is a kind of cheering)
'partners in prison having no right' is the wordplay.
I cannot really understand how this works, but
'partners' could be 'ns' (North and South are partners in the game bridge) and 'ns' is located in the answer.
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
The remaining letters 'cole' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for console that I've seen before include "Comfort - cabinet" , "Calm" , "stops may be arranged here" , "Give comfort to (someone) for a loss" , "where the organist sits" .)
