Some get a rollicking over talk (5)
I believe the answer is:
orate
'talk' is the definition.
(orating is a kind of talking)
'some get a rollicking over' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'over' is a reversal indicator.
'etaro' can be found hidden inside 'get a rollicking'.
'etaro' in reverse letter order is 'ORATE'.
(Other definitions for orate that I've seen before include "Talk pompously" , "Erato (anag.)" , "Speak like Cicero?" , "talk at length" , "Speak publicly" .)
