Worker in wood seeing grouse on log (9)
I believe the answer is:
carpenter
'worker in wood' is the definition.
'carpenter' can be an answer for 'worker' (carpenter is a kind of worker). I'm unsure of the 'in wood' bit.
'grouse on log' is the wordplay.
'grouse' becomes 'carp' (both can mean to complain).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'log' becomes 'enter' (as in logging or entering information to a record).
'carp'+'enter'='CARPENTER'
'seeing' is the link.
Can you help me to learn more?
(Other definitions for carpenter that I've seen before include "artisan" , "Wood worker" , "Chippy" , "Find fault with record" , "tradesman" .)
