This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "ratiocination" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "ratiocination" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "ratiocination" with a nearby alternative so the final choice matches both meaning and reader expectation.
Check whether "ratiocination" is acting as noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
Compare it with "abstract thought" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Before publishing a sentence with "ratiocination", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.
"But it will be apparent from the refutation of the ſecond Falſification, wherewith you charge the Author of the Letters, that theſe miſchievous conſequences are rightly drawn from the wicked principle layd down by Vaſquez [Gabriel Vásquez] in the ſame place, and accordingly, that that Jeſuit hath not done violence to the rules of ratiocination, but to thoſe of the Goſpel."
"Finally Tao comes to possess the meaning of “rational speech” or “word,” and in this sense it closely resembles the Greek Logos, for in addition to its philosophical significance the term Tao touches a religious chord in the souls of the Chinese just as did the word Logos among the Platonists and the Greek Christians. […] The Tao of man, jan tao [footnote: 人道], is the process of ratiocination, and as such it is fallible; but there is an Eternal Reason, ch‘ang tao [footnote: 常道], also called t‘ien tao [footnote: 天道], “Heaven’s Reason,” i.e., the world-order which shapes all things, and the burden of Lao-tze’s message is to let this Heaven’s Reason or Eternal Reason prevail."
"Where the Qur’an has not been explicit, the Hadith has often supplied guidance, providing an intermediate source of knowledge between the text of the Holy Book itself and the ratiocinations of the religious lawyers, the fuqaha’, who had recourse, when all else failed, to such principles as analogical reasoning and personal judgement."

Pronounced /ɹætɪˌɒsɪˈneɪʃn̩/.
Borrowed from French ratiocination, from Latin ratiōcinātiō (“argumentation, reasoning, ratiocination; a syllogism”), from ratiōcinātus (“reckoned”) + -tiō (suffix forming a noun relating to some action or the result of an action). Ratiōcinātus is the perfect passive participle of ratiōcinor (“to compute, reckon; to argue, infer”), from ratiō (“reason, explanation”) (from reor (“to calculate, reckon”), possibly from Proto-Italic *rēōr, from Proto-Indo-European *h₂reh₁- (“to put in order”)) + -cinor, modelled after vāticinor (“to foretell, prophesy”), equivalent to ratiocinate + -ion.
