English, the old girl carrying good visual aid
I believe the answer is:
eyeglass
'visual aid' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'english the old girl carrying good' is the wordplay.
'english' becomes 'e' (abbreviation).
'the old' becomes 'ye'.
'girl' becomes 'lass' (lass is a kind of girl**).
'carrying' says to put letters next to each other.
'good' becomes 'g' (abbreviation).
'lass' after 'g' is 'glass'.
'e'+'ye'+'glass'='EYEGLASS'
Can you help me to learn more?
(Other definitions for eyeglass that I've seen before include "Monocle, or spectacles in plural" , "Lens for aiding defective vision" , "Aid to vision" .)
