Is bound to be a bit hasty (3)
I believe the answer is:
has
'is' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their -s form.
Maybe you can see an association between them that I can't see?
'bound to be a bit hasty' is the wordplay.
'bound' becomes 'as' (I can't justify this - if you can you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'be a bit' indicates taking the first letters (I've seen 'a bit of' mean this).
The initial letter of 'hasty' is 'h'.
'as' after 'h' is 'HAS'.
Can you help me to learn more?
(Other definitions for has that I've seen before include "Gives birth to" , "Contains" , "Owns, holds" , "Possesses or owns" , "Bears" .)
