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' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'ran'+'t'='RANT'
'for' acts as a link.
(Other definitions for rant that I've seen before include "Speak wildly and incoherently" , "bombast" , "Angry outburst" , "Loud and emotional declamation" , "Harangue, rave" .)
