Assignations (6)
I believe the answer is:
trysts
'assignations' is the definition.
('tryst' can be a synonym of 'assignation')
This is all the clue.
(Other definitions for trysts that I've seen before include "Lover's appointments" , "'Assignations, romantic meetings (6)'" , "Lovers' meetings" , "dates" , "Lovers' assignations" .)
