Club once used to get old writer going? (7)
I believe the answer is:
niblick
'club' is the definition.
(historical type of golf club)
'used to get old writer going?' is the wordplay.
I cannot really see how this works, but
'get' could be 'lick' (synonyms) and 'lick' is found within the answer.
'writer' could be 'nib' (something which writes) and 'nib' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'once' acts as a link.
Can you help me to learn more?
(Other definitions for niblick that I've seen before include "Old golf club" , "old-fashioned club" , "Golf iron" , "Old iron" , "number eight say" .)
