Companion of Tom and Dick
I believe the answer is:
'companion' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for harry that I've seen before include "Torment by constant attack" , "Persistently harass" , "English prince - trouble" , "Make repeated attacks on, badger" , "Wizard Potter" .)
