From the right quarter (8)
I believe the answer is:
easterly
'quarter' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'from the right' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for easterly that I've seen before include "bitter blow for the UK" , "Wind coming from Britain, say" , "Of wind, blowing from direction of rising sun" , "Invariably cold wind" , "The sort of wind that brings cold air to this country" .)
