Tumble, being tackled by excellent hooker (7)
I believe the answer is:
trollop
'hooker' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'tumble being tackled by excellent' is the wordplay.
'tumble' becomes 'roll' (tumble can mean to fall or roll).
'being tackled' means one lot of letters goes inside another.
'by excellent' becomes 'top' (top can mean the best. I am not sure about the 'by' bit.).
'roll' inserted within 'top' is 'TROLLOP'.
Can you help me to learn more?
(Other definitions for trollop that I've seen before include "person of dubious morality" , "loose woman" , "Shameless woman" , "Promiscuous woman" , "Baggage" .)
