A crime admitted by company providing better accommodation (6)
I believe the answer is:
casino
'better accommodation' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'a crime admitted by company' is the wordplay.
'crime' becomes 'sin'.
'admitted by' indicates putting letters inside.
'company' becomes 'co' (abbreviation).
'a'+'sin'='asin'
'asin' going inside 'co' is 'CASINO'.
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for casino that I've seen before include "Where some gamblers go" , "Gambling establishment" , "Las Vegas establishment" , "gambling-place" , "Gaming house" .)
