Lexicographers do not agree on the date of appearance of this expression with its current meaning. For some, it dates from 1727, for others from the middle of the XNUMXth century.
On the other hand, they agree perfectly to agree that the old word noah which is cited in 1640, comes from the root nah- ou nam- which, it seems, gave birth to many childish words in different regional dialects.
Nanan, with a capital letter, first designated meat, then, in the children's world, it was very quickly used to designate a treat, then, by extension, something delicious.
By extension always, the expression has also taken the meaning of "it is easy" which is to be compared to It's a piece of cake!
