Applicable experience again taking a time (8)
I believe the answer is:
relative
'applicable' is the definition.
(thesaurus)
'experience again taking a time' is the wordplay.
'experience again' becomes 'relive' ('live' is an answer for 'experience' so perhaps 'relive' is OK for 'experience again').
'taking' means one lot of letters goes inside another.
'time' becomes 't' (abbreviation).
'a'+'t'='at'
'relive' going around 'at' is 'RELATIVE'.
(Other definitions for relative that I've seen before include "uncle, say" , "One connected by blood or marriage" , "Kinsman" , "one in a family" , "Person connected by blood or marriage" .)
