Without a partner making one run (6)
I believe the answer is:
single
'one run' is the definition.
(type of run in cricket)
'without a partner' is the wordplay.
I cannot quite see how this works, but
'partner' could be 's' and 's' is found in the answer.
The remaining letters 'ingle' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'making' acts as a link.
Can you help me to learn more?
(Other definitions for single that I've seen before include "Ticket To Ride < : > hit" , "Sole" , "Not in a relationship" , "Not married, just the one" , "Like bachelor" .)
