Is he suspended? (3)
I believe the answer is:
bob
'is he' is the definition.
(short for Robert)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bob that I've seen before include "Briefly curtsy; hair style" , "short hair" , "Pre-decimal coin" , "Move up and down as in water" , "Bow" .)
