It's well said that speech without an introduction can be stylish, in a manner of speaking (8)
I believe the answer is:
locution
'manner of speaking' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for locution that I've seen before include "Style of speech or idiom" , "way of speaking" , "utterance" , "Person's style of speech" , "Phase or style of speech" .)
