Think there’s no time to step in (7)
I believe the answer is:
mediate
'step in' is the definition.
(thesaurus)
'think there's no time' is the wordplay.
'think' becomes 'meditate' (meditating is a kind of thinking).
'there's no' is a deletion indicator.
'time' becomes 't' (abbreviation).
'meditate' with 't' taken out is 'MEDIATE'.
'to' is the link.
(Other definitions for mediate that I've seen before include "Act as intermediary" , "Act as negotiator or peacemaker" , "Act between parties to reconcile differences" , "try to resolve dispute" , "Act as middle man" .)
