"""OK, now define "the folk idiom" (without using the word 'folk'in the definition)."""

I've always interpreted this to mean "In the style, manner, or format of the tradition".

Richard Bridge, who has been the staunchest supporter of the 1954 definition has commented in the past that some of my original material, while it is not "Folk", is created "in the style of the tradition".

This is a critique I can easily live with.
