surmise

The English verb "surmise," meaning to suppose something is true without conclusive evidence, traces‍​‍​‍​‌​‌​‌​‍​‍​‌​‌​‍​‍​‌​‌​‌​‌​‌​‍​‌​‍​‌​‌​‍​‌​‌​‌​‍​‌​‍​‍​‍​‌ its etymological roots to the Latin verb supermittere, which itself is a compound of the prefix super- and the verb mittere. The prefix super- in Latin conveys the sense of "over," "upon," or "above," while mittere means "to send," "to let go," or "to release." Thus, supermittere literally signifies "to send over" or "to throw upon."

The pathway from supermittere to the English "surmise" passes through Old French. In Old French, the verb surmettre meant "to accuse," "to charge," or "to throw upon," reflecting a legal context where an accusation or charge was metaphorically "thrown upon" someone. The past participle of surmettre was surmis, which evolved into the noun surmise in Anglo-French, denoting an accusation or a charge. This Anglo-French form entered Middle English in the 15th century, initially retaining the sense of a formal accusation or charge.

The semantic evolution of "surmise" is notable for its shift from a concrete legal accusation to a more abstract notion of conjecture or supposition without firm evidence. Originally, a surmise was a formal allegation made against someone, something "thrown upon" them before proof was established. Over time, this sense weakened epistemically, moving from an assertive claim requiring proof to a tentative guess or hypothesis. This semantic weakening reflects a broader linguistic tendency for words denoting strong assertions to evolve into terms for weaker, more tentative statements.

The Latin root mittere is highly productive and underlies a large family of English words related to the act of sending or dispatching. Examples include admit (to send in), commit (to send together or entrust), dismiss (to send away), emit (to send out), intermission (a sending between), missile (something sent or thrown), mission (a sending or dispatch), permit (to send through or allow), promise (to send forward or guarantee), remit (to send back), submit (to send under or yield), and transmit (to send across). Each of these words shares the core semantic element of sending or dispatching, illustrating the centrality of mittere in the Latin verbal system and its extensive influence on English vocabulary.

The prefix super- also appears in numerous English words, often conveying the sense of "above," "beyond," or "over." Examples include supervise (to oversee), superimpose (to place over), and supernatural (beyond the natural). In the case of surmise, super- combines with mittere to produce a compound verb that metaphorically involves "throwing upon" or "sending over" an accusation or charge.

It is important to distinguish the inherited Latin roots from later borrowings or cognates. The English word "surmise" is a borrowing from Anglo-French, itself derived from Old French, which in turn comes from Latin. This is not an inherited word from Proto-Indo-European via Old English, but rather a loanword introduced during or after the Norman Conquest, when Anglo-Norman French heavily influenced English vocabulary, especially in legal and administrative domains.

The earliest attestations of "surmise" in English date to the 15th century, consistent with the period when Anglo-French legal terminology was being absorbed into English. The original legal sense of a formal accusation gradually gave way to the modern meaning of a supposition or conjecture, reflecting a semantic shift from a concrete legal context to a more general epistemic context.

"surmise" derives from the Latin supermittere, composed of super- ("over, upon") and mittere ("to send"). It entered English via Anglo-French surmise, originally meaning a formal accusation or charge. Over time, the meaning shifted from a legal allegation to a tentative supposition without firm evidence. This semantic evolution illustrates the weakening of epistemic certainty inherent in the word’s history. The Latin mittere root is prolific in English, contributing to a broad semantic field centered on sending or dispatching, while super- provides the spatial or metaphorical sense of "over" or "upon." The word "surmise" thus encapsulates a rich linguistic history from Latin legal terminology to modern English epistemic vocabulary.
