Works in the stable and yard with tramp's companion (4)
I believe the answer is:
lady
'tramp's companion' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'works in the stable and yard' is the wordplay.
'works in the stable' becomes 'lad' (I can't justify this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'yard' becomes 'y'.
'lad'+'y'='LADY'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for lady that I've seen before include "older female" , "Luck, for example" , "mature woman" , "Lord's wife - peeress's title" , "High-class woman" .)
