So, “idyot” appears to be different from “hediyot” , this one preceeding the Greek Hellenic and Roman civilizations by many centuries,
HEDYOT(From Gr. [G]); (a) a commoner or layman, as opposed to a king or High Priest; (b) an ignorant or ill-mannered man; (c) untrained, as opposed to a skilled worker; (d) private writings, as opposed to biblical books.
By the way, yesterday you claimed that „hedyot” entered Hebrew in Second Temple era (530 BC – 70 AC). Today you claim that it precedes Hellenic civilization (510Bc – 323 BC) by many centuries. Make up your mind. It is either from Second Temple era or it precedes Greece by many centuries. If it really precedes Greece – then prove it.
