Endure time inside for example (4)
I believe the answer is:
stay
'endure' is the definition.
(thesaurus)
'time inside for example' is the wordplay.
'time' becomes 't' (abbreviation).
'inside' means one lot of letters goes inside another.
'for example' becomes 'say' ('say' can be used to introduce an example).
't' inserted inside 'say' is 'STAY'.
(Other definitions for stay that I've seen before include "Don't go!" , "Remain; prop" , "Wait" , "Stanchion" , "Corset strut" .)
