Origin of notion
Related formsno·tion·less, adjective
In the comedies of Plautus, nōtiō meant “acquaintance (with a person).” In legal and juridical language, nōtiō meant “examination, inquiry (by a magistrate).” The usual meaning of notion we owe to Cicero, the Roman orator, statesman, and man of letters, who created a technical philosophical vocabulary for Latin almost single-handedly in order to translate concepts in Greek philosophy. In his Topica (31), Cicero explains his usage of nōtiō : “I mean by notion what the Greeks call énnoia [‘thinking, reflection, notion, concept’] or prólēpsis [‘preconception, mental picture’].”
The plural notions “small articles, such as buttons, thread, ribbon, etc., displayed together for sale” was an Americanism that first appeared in a Philadelphia newspaper in 1796.
