Propels, in a way (4)
I believe the answer is:
oars
'propels in a way' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oars that I've seen before include "Propelling implements" , "Sweeps" , "Soar around the rowers" , "Rowing blades" , "Busy bodies usually stick them in, also used in rowing" .)
