Be naked and free (4,7,2)
I believe the answer is:
have nothing on
'free' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps there's an association between them I don't understand?
'be naked and' is the wordplay.
I cannot really understand how this works, but
'be' could be 'go' (going is a kind of being) and 'go' is located in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for have nothing on that I've seen before include "Be uncommitted" , "like Gypsy Rose Lee ultimately" , "barely?" , "being out of gear?" , "Be free" .)
