Arrogant and elated Ruth (6)
I believe the answer is:
uppity
'arrogant' is the definition.
(I've seen this in another clue)
'elated ruth' is the wordplay.
'elated' becomes 'up' (I can't explain this - if you can you should give a lot more credence to this answer).
'ruth' becomes 'pity' (synonyms).
'up'+'pity'='UPPITY'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for uppity that I've seen before include "Informally pert or arrogant" , "Not easily persuaded" , "Informally presumptuous or arrogant" , "Cheeky or presumptuous" , "Informally presumptuous or self-important" .)
