Hold forth in elaborate style, concealing name (5)
I believe the answer is:
orate
'hold forth' is the definition.
(I've seen this before)
'elaborate style concealing name' is the wordplay.
'ORATE' is hidden within the letters.
However, I'm not sure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for orate that I've seen before include "Harangue" , "Erato (anag.)" , "Lecture" , "Speak pompously and at length" , "make speeches" .)
