Fellow offering information: article about return of thaw (9)
I believe the answer is:
gentleman
'fellow' is the definition.
(I've seen this before)
'information article about return of thaw' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'article' becomes 'an' (English indefinite article).
'about' says to put letters next to each other.
'return of' is a reversal indicator.
'thaw' becomes 'melt' (synonyms).
'melt' in reverse letter order is 'tlem'.
'an' put after 'tlem' is 'tleman'.
'gen'+'tleman'='GENTLEMAN'
'offering' is the link.
(Other definitions for gentleman that I've seen before include "Male of refinement" , "Courteous chap" , "Toff" , "-'s -; - farmer" , "Courteous fellow" .)
