Ground rule hit string-puller? (7)
I believe the answer is:
luthier
'string-puller?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'ground rule hit' is the wordplay.
'ground' is an anagram indicator ('grind' the letters into a new form).
'rule'+'hit'='rulehit'
'rulehit' is an anagram of 'LUTHIER'.
Can you help me to learn more?
(Other definitions for luthier that I've seen before include "maker of musical instruments" , "Maker of stringed instruments" .)
