Made verbal contribution identifying part of wheel (5)
I believe the answer is:
spoke
I believe this is a double definition.
'made verbal contribution' is the first definition.
(spoke some words)
'part of wheel' is the second definition.
(I know that spoke part of bicycle wheel)
'identifying' is the link.
(Other definitions for spoke that I've seen before include "Radius" , "Rung" , "Wheel's radial member" , "gave address" , "Uttered - bicycle wheel part" .)
