Gets on to Peg, who won't talk to one on the phone (5,2)
I believe the answer is:
hangs up
'gets on' is the definition.
The definition and answer can be both related to change as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'peg who won't talk to one on the phone' is the wordplay.
I cannot really understand how this works, but
'one' could be 'an' (I've seen this in other clues) and 'an' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for hangs up that I've seen before include "Gets off" , "puts on the line" .)
