Can consumed after yobbish regulars suggest they're stubborn (9)
I believe the answer is:
obstinate
'stubborn' is the definition.
(I know that stubborn can be written as obstinate)
'can consumed after yobbish regulars' is the wordplay.
'can' becomes 'tin' (both are metal containers).
'consumed' becomes 'ate' (to eat is to consume food).
'after' says to put letters next to each other.
'regulars' means one should take alternating letters (letters selected at regular intervals).
The alternate letters of 'yobbish' are 'obs'.
'tin'+'ate'='tinate'
'tinate' put after 'obs' is 'OBSTINATE'.
'suggest they're' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for obstinate that I've seen before include "Stubbornly persistent" , "Blindly stubborn" , "Like mules" , "Female bird" , "Mulish" .)
