Sunday talk (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
sermon
'sunday talk' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sermon that I've seen before include "Tedious admonition" , "Reproving speech (delivered on the Mount?)" , "Homily" , "Pulpit speech" , "Talk delivered during industrial dispute" .)
