The fruit of engagements? (5)
I believe this is a double definition.
'the fruit' is the first definition.
(I've seen this before)
'engagements?' is the second definition.
('date' can be a synonym of 'engagement')
'of' acts as a link.
(Other definitions for dates that I've seen before include "Fruits for social engagements", "Occasions", "Dried fruit", "Takes out", "becomes less fresh".)
