Agree to meet (8)
I believe the answer is:
coincide
This clue is a double definition.
'agree' is the first definition.
(coinciding is a kind of agreeing)
'meet' is the second definition.
(thesaurus)
'to' acts as a link.
(Other definitions for coincide that I've seen before include "Occur at same time, place" , "match" , "Happen together" , "Occur together" , "Happen simultaneously" .)
