Fruit shows its age (5)
I believe the answer is:
dates
'its age' is the definition.
I can't judge whether this defines the answer.
'fruit shows' is the wordplay.
'fruit' becomes 'date' (date is a kind of fruit).
'shows' becomes 's' (this might be a standard abbreviation of which I'm unaware).
'date'+'s'='DATES'
Can you help me to learn more?
(Other definitions for dates that I've seen before include "Fruit - shows its age" , "Sweet edible fruits of a palm" , "Meetings arranged in advance" , "Sated (anag) - fruit" , "appearing on most coins" .)
