Fugitive getting away with time inside (8)
I believe the answer is:
fleeting
'fugitive' is the definition.
(I know that fugitive can be written as fleeting)
'away with time inside' is the wordplay.
I cannot really understand how this works, but
'time' could be 't' (abbreviation) and 't' is found in the answer.
'inside' could be 'in' and 'in' is found within the answer.
This explanation may well be incorrect...
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for fleeting that I've seen before include "Passing quickly, transitory" , "Transient" , "Lasting for a brief time" , "Evanescent" , "fast" .)
