Annual fruit (5)
I believe the answer is:
dates
'fruit' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dates that I've seen before include "Specified parts of the year" , "Meetings arranged in advance" , "Small tree-fruits or social appointments" , "appearing on most coins" , "Fruits and pre-arranged meetings" .)
