Rough-and-ready way to score (7)
I believe the answer is:
scratch
'score' is the definition.
(thesaurus)
'rough-and-ready way' is the wordplay.
I cannot quite understand how this works, but
'way' could be 's' (Compass direction - South) and 's' is located in the answer.
The remaining letters 'cratch' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for scratch that I've seen before include "Score with a sharp point" , "haphazard a team?" , "Lacerate" , "Withdraw from (competition)" , "Receiving no allowance < , ready" .)
