Next time, Jade can change first (8)
I believe the answer is:
adjacent
'next' is the definition.
(synonyms)
'time jade can change first' is the wordplay.
'time' becomes 't' (abbreviation).
'change' indicates anagramming the letters.
'first' is a charade indicator (letters next to each other).
'jade'+'can'='jadecan'
'jadecan' is an anagram of 'adjacen'.
't' put after 'adjacen' is 'ADJACENT'.
(Other definitions for adjacent that I've seen before include "Contiguous" , "Adjoining, lying near" , "Near - juxtaposed" , "Alongside" , "Abutting" .)
