Is bound to be in haste (3)
I believe the answer is:
has
'is' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their -s form.
Maybe you can see a link between them that I can't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for has that I've seen before include "Cheats" , "Possesses or owns" , "Bears" , "suffers from" , "Owns, holds" .)
