OK, Elva, iterate it clearly that it is not negotiable (4,2,2,5,2)
I believe the answer is:
take it or leave it
'ok elva iterate it clearly that it is not negotiable' is the definition.
The answer and definition are not the same part of speech.
'ok elva iterate it clearly that it is not negotiable' is the wordplay.
'ok elva iterate it' anagrams to 'TAKE IT OR LEAVE IT'.
But, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for take it or leave it that I've seen before include "Clear choice for one tempted to thieve" , "Two options for the burglar" , "no more concessions" , "Two options for the gin drinker" , "Please yourself" .)
