Hear a way to form a meeting (5)
I believe the answer is:
tryst
'a meeting' is the definition.
(I know that tryst is a type of appointment)
'hear a way' is the wordplay.
'hear' becomes 'try' (to hear or try a case in the legal sense).
'a way' becomes 'st' (abbreviation for street).
'try'+'st'='TRYST'
'to form' is the link.
(Other definitions for tryst that I've seen before include "(Secret) meeting between lovers" , "Secret rendezvous between lovers" , "Rendezvous - assignation" , "private meeting" , "Romantic rendezvous (literary)" .)
