Provide entertainment for those on the watch! (8)
I believe the answer is:
televise
'watch' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for televise that I've seen before include "Broadcast visual images" , "Put on TV (S, not Z)" , "Air, broadcast" , "Put on the box" , "Show" .)
