different between ratiocination vs discursus

English

Etymology

Borrowed from French ratiocination, from Latin rati?cin?ti? (“argumentation, reasoning, ratiocination; a syllogism”), from rati?cin?tus (“reckoned”) + -ti? (“suffix forming a noun relating to some action or the result of an action”). Rati?cin?tus is the perfect passive participle of rati?cinor (“to compute, reckon; to argue, infer”), from rati? (“reason, explanation”) (from reor (“to calculate, reckon”), possibly from Proto-Italic *r??r, from Proto-Indo-European *h?reh?- (“to put in order”)) + -cinor, modelled after v?ticinor (“to foretell, prophesy”), equivalent to ratiocinate +? -ion.
