Something frivolous from female Pulitzer Prize winner (5)
I believe the answer is:
froth
'winner' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for froth that I've seen before include "Spume or foam" , "Mass of small bubbles" , "Effervesce" , "Small bubbles on a liquid" , "Lather" .)
