Such a cat might be a man (8)
I believe the answer is:
tailless
'such' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'a cat might be a man' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'man' could be 'les' and 'les' is present in the answer.
The remaining letters 'tils' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tailless that I've seen before include "Physical condition of Manx cat" , "Like frogs and toads, say" , "Physical characteristic of Manx cat" .)
