Triumph direct from last month (5)
I believe the answer is:
exult
'triumph' is the definition.
(I know that triumph can be written as exult)
'direct from last month' is the wordplay.
'direct from' becomes 'ex' (I've seen this in other clues).
'last month' becomes 'ult' (short for 'last month' in correspondence).
'ex'+'ult'='EXULT'
(Other definitions for exult that I've seen before include "Rejoice exceedingly, revel in" , "Feel or express triumph" , "Rejoice greatly" , "Jubilate" , "Rejoice exceedingly, glory in (5)" .)
