Word of thanks with poet getting ceremonial tunic (6)
I believe the answer is:
tabard
'ceremonial tunic' is the definition.
'word of thanks with poet' is the wordplay.
'word of thanks' becomes 'ta'.
'with' is a charade indicator (letters next to each other).
'poet' becomes 'bard' (bard is a kind of poet).
'ta'+'bard'='TABARD'
'getting' is the link.
(Other definitions for tabard that I've seen before include "Jacket worn by a herald" , "[A] top" , "Sleeveless jerkin" , "Sleeveless jacket" , "Gilet" .)
