One gets it in time (5)
I believe the answer is:
older
'one' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'it in time' is the wordplay.
I cannot really see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
'time' could be 'old' (old is a kind of time) and 'old' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'gets' is the link.
Can you help me to learn more?
(Other definitions for older that I've seen before include "Increasingly mature" , "Of greater age (O, not E)" , "Advanced in years (but wiser?)" , "Less young" , "Earlier" .)
