Would hide treater try to capture old queen? (7)
I believe the answer is:
tannery
'would hide treater' is the definition.
I can't judge whether this definition defines the answer.
'try to capture old queen?' is the wordplay.
'to capture' is an insertion indicator.
'old queen?' becomes 'Anne' (Queen Anne, 18th-century queen).
'try' enclosing 'anne' is 'TANNERY'.
Can you help me to learn more?
(Other definitions for tannery that I've seen before include "skin treatment facility" , "Leather-processing plant" , "Where hides are made into leather" , "where hides are treated" , "Building involved in making leather" .)
