Managed to find time for rage (4)
I believe the answer is:
rant
'rage' is the definition.
(thesaurus)
'managed to find time' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'to find' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'ran'+'t'='RANT'
'for' is the link.
(Other definitions for rant that I've seen before include "Speak wildly and incoherently" , "bombast" , "Angry outburst" , "Loud and emotional declamation" , "Harangue, rave" .)
