Speech offering worship putting a daughter off (7)
I believe the answer is:
oration
'speech' is the definition.
(oration is a kind of speech)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for oration that I've seen before include "lecture" , "Ontario (anag)" , "words" , "Power of speech" , "Making a speech" .)
