Show some of the ravages of time (3)
I believe the answer is:
age
'time' is the definition.
(an age is a period of time)
'show some of the ravages of' is the wordplay.
'show some of' indicates a hidden word (I've seen 'show some' mean this (I've seen this in other clues)).
'AGE' is hidden in the letters of 'ravages of'.
(Other definitions for age that I've seen before include "Plenty of time" , "Period piece" , "Era; grow old" , "Period of time" , "Years lived so far" .)
