Say Hutton's better being cover (4,3)
I believe the answer is:
lens cap
'cover' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'say hutton's better' is the wordplay.
I cannot really understand how this works, but
'hutton's' could be 'lens' (cricketer Len Hutton) and 'lens' is located in the answer.
'better' could be 'cap' (both can mean to beat somebody else's attempt) and 'cap' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'being' acts as a link.
Can you help me to learn more?
(Other definitions for lens cap that I've seen before include "Camera cover" , "protection for photographer" , "Aperture protector" .)
