A hut built for headless writer (6)
I believe the answer is:
author
'writer' is the definition.
(synonyms)
'a hut built for headless' is the wordplay.
'built' is an anagram indicator.
'headless' means to remove the first letter.
'for' with its first letter removed is 'or'.
'hut' is an anagram of 'uth'.
'a'+'uth'+'or'='AUTHOR'
(Other definitions for author that I've seen before include "Ours wrote as Edward" , "Writer of a book or play" , "Writer of a book, say" , "Generator of written work" , "eg Novelist" .)
