Go and make a speech about training (7)
I believe the answer is:
operate
'go' is the definition.
(operating is a kind of going)
'make a speech about training' is the wordplay.
'make a speech' becomes 'orate' (I've seen this before).
'about' means one lot of letters goes inside another.
'training' becomes 'pe'.
'orate' going around 'pe' is 'OPERATE'.
'and' is the link.
(Other definitions for operate that I've seen before include "Cut - run" , "Perform as surgeon does" , "effect" , "Make function" , "Function; run" .)
