Test way to secure date (5)
I believe the answer is:
tryst
'date' is the definition.
(I know that tryst is a class)
'test way' is the wordplay.
'test' becomes 'try' (synonyms).
'way' becomes 'st' (abbreviation for street).
'try'+'st'='TRYST'
'to secure' is the link.
(Other definitions for tryst that I've seen before include "Romantic assignation" , "Romantic rendezvous (literary)" , "Rendezvous - assignation" , "Romantic meeting" , "cattle-fair" .)
