Is oiler able to go finally, with America picking quarrels? (12)
I believe the answer is:
cantankerous
'is oiler able to go finally with america picking quarrels?' is the definition.
I can't tell whether this defines the answer.
'is oiler able to go finally with america' is the wordplay.
I cannot really see how this works, but
'oiler' could be 'tanker' (synonyms) and 'tanker' is located in the answer.
'able' could be 'can' and 'can' is found in the answer.
'america' could be 'us' (United States) and 'us' is found in the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cantankerous that I've seen before include "Disagreeable" , "Irritable" , "Irascible" , "Stubbornly obstructive" , "Grouchy" .)
