The lady with the fringe gets the whole caboodle! (7)
I believe the answer is:
shebang
'the whole caboodle' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'the lady with the fringe' is the wordplay.
'the lady' becomes 'she' ('she' refers to a woman).
'with' means one lot of letters go next to another.
'the fringe' becomes 'bang' (I've seen this before).
'she'+'bang'='SHEBANG'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for shebang that I've seen before include "affair in America" , "Matter" , "The entire system" , "The whole thing?" , "The whole ___ (entirely)" .)
