Managed to find time for tirade (4)
I believe the answer is:
rant
'tirade' is the definition.
(both can mean an angry outburst)
'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' acts as a link.
(Other definitions for rant that I've seen before include "Intemperate speech" , "Wild speech" , "Shout wildly at length" , "Loud and emotional declamation" , "Talk wildly or violently" .)
