Beginning to object over unfriendly atmosphere (5)
I believe the answer is:
odour
'atmosphere' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's an association between them I don't understand?
'beginning to object over unfriendly' is the wordplay.
'beginning to' indicates taking the first letters.
'over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'unfriendly' becomes 'dour'.
The first letter of 'object' is 'o'.
'o'+'dour'='ODOUR'
Can you help me to learn more?
(Other definitions for odour that I've seen before include "Aroma or fragrance" , "Whiff" , "reputation" , "Smell, redolence" , "for the nose to detect" .)
