Still time for adventure (5)
I believe the answer is:
event
'adventure' is the definition.
(thesaurus)
'still time' is the wordplay.
'still' becomes 'even' (synonyms).
'time' becomes 't' (abbreviation).
'even'+'t'='EVENT'
'for' acts as a link.
(Other definitions for event that I've seen before include "Something going on" , "long jump, say" , "Occurence, happening" , "Incident, occurrence" , "'Occurrence, happening (5)'" .)
