It's possibly true, Ted said (7)
I believe the answer is:
uttered
'said' is the definition.
(I've seen this in another clue)
'it's possibly true ted' is the wordplay.
'it's possibly' indicates an anagram.
'true'+'ted'='trueted'
'trueted' is an anagram of 'UTTERED'.
(Other definitions for uttered that I've seen before include "Said (something)" , "Spoken" , "Spoke and put into circulation" , "Pronounced" , "In law, put forged money into circulation" .)
