Yours truly set new encounters (5)
I believe the answer is:
meets
'encounters' is the definition.
(I know this)
'yours truly set new' is the wordplay.
'yours truly' becomes 'me' ().
'new' is an anagram indicator.
'set' with letters rearranged gives 'ets'.
'me'+'ets'='MEETS'
(Other definitions for meets that I've seen before include "Comes together with others" , "Joins with" , "Comes into contact with" , "Encounters, perhaps by appointment" , "Makes contact with" .)
