Odd elements of party interfere (3)
I believe the answer is:
pry
'interfere' is the definition.
(I've seen this before)
'odd elements of party' is the wordplay.
'odd elements of' indicates alternate letters (only the odd-numbered letters are used).
The alternating letters of 'party' are 'PRY'.
(Other definitions for pry that I've seen before include "Look intrusively" , "act curiously" , "Be nosey" , "Look inquisitively into private matters" , "Be inquisitive" .)
