Celebrity gets some men terribly worn out! (6)
I believe the answer is:
renown
'celebrity' is the definition.
(I know that celebrity can be written as renown)
'some men terribly worn out' is the wordplay.
'some' means to look at the middle letters.
'men' becomes 'crew' (I've seen this in another clue).
'terribly worn out' becomes 'nown' (I can't explain this - if you can you should give a lot more credence to this answer).
The central letters of 'crew' are 're'.
're'+'nown'='RENOWN'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for renown that I've seen before include "Plane's maximum width" , "Fame, respect" , "Fame and distinction" , "Fame and public acclamation" , "Good reputation" .)
