He may well be suspended (3)
I believe the answer is:
bob
'he' is the definition.
(short for Robert)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for bob that I've seen before include "Quick curtsy" , "Move up and down like Robert" , "Brief curtsy - hairstyle" , "Move up and down as in water" , "-- Dylan, singer" .)
