Thespian has worn coat to the end of winter (5)
I believe the answer is:
actor
'thespian' is the definition.
(synonyms)
'worn coat to the end of winter' is the wordplay.
'worn' indicates an anagram (worn can mean damaged).
'to the end of' says to take the final letters.
The final letter of 'winter' is 'r'.
'coat' with letters rearranged gives 'acto'.
'acto'+'r'='ACTOR'
'has' is the link.
(Other definitions for actor that I've seen before include "Croat (anag.)" , "One on stage" , "Film star" , "Gielgud, say" , "One taking part" .)
