Quick to help the erring player? (6)
I believe the answer is:
prompt
This could be a double definition.
'quick' is the first definition.
(I know that quick can be written as prompt)
'help the erring player?' is the second definition.
'prompt' can be an answer for 'help' (thesaurus). I am unsure of the 'the erring player?' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for prompt that I've seen before include "Bang on" , "Cause; on time" , "keeping to the right time" , "Bring about; done without delay" , "Ready" .)
