Speaker absorbed by Chancellor, a Tory? (6)
I believe the answer is:
'speaker' is the definition.
(I know that orator is a type of speaker)
'absorbed by chancellor a tory?' is the wordplay.
'absorbed by' says the answer is hidden in the clue.
'ORATOR' is hidden within 'chancellor a tory'.
(Other definitions for orator that I've seen before include "An impressive public speaker" , "Rhetorician" , "A Rhetorical talker or speech-maker" , "One who holds forth" , "Formal speech maker" .)
