As worn by good girls? (7)
I believe the answer is:
glasses
'as worn by good girls?' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'by good girls?' is the wordplay.
'by' is a charade indicator (letters next to each other).
'good' becomes 'g' (abbreviation).
'girls?' becomes 'lasses' (lass can mean a girl).
'g'+'lasses' is 'GLASSES'.
Can you help me to learn more?
(Other definitions for glasses that I've seen before include "Spectacles and receptacles" , "are they full of alcohol?" , "Spectacles or drinking containers" , "Spectacles; schooners" , "Drinks" .)
