Admires words from the bride and groom -- tales about intentions, ultimately (8)
I believe the answer is:
idolises
'admires' is the definition.
(I've seen this before)
'words from the bride and groom tales about intentions ultimately' is the wordplay.
'words from the bride and groom' becomes 'ido' (I've seen this in another clue).
'tales' becomes 'lies'.
'about' is an insertion indicator.
'ultimately' indicates one should take the final letters.
The final letter of 'intentions' is 's'.
'lies' enclosing 's' is 'lises'.
'ido'+'lises'='IDOLISES'
(Other definitions for idolises that I've seen before include "Reveres, adores" , "Worships and adores" , "Thinks the world of" , "Greatly reveres" , "admires" .)
