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