What does consentaneous mean?
Consentaneous is a formal, now rather rare English adjective meaning agreeing, accordant, or harmonious with something else. When a decision, opinion, or action is described as consentaneous, it is understood to be fully in step with some standard, wish, or prevailing view — for example, a ruling that was consentaneous with the advice of a committee. The word derives from the Latin consentaneus, built on consentire ('to feel together'), the same root behind 'consent' and 'consensus'. It entered English in the seventeenth century and appears chiefly in legal, theological, and scholarly texts, often paired with the suffix '-aneous' shared by words like 'spontaneous'. Because of its rarity, consentaneous lends writing a distinctly archaic and erudite tone; modern readers are far more likely to encounter its plainer equivalents such as 'consistent' or 'in agreement'. Its adverbial derivative, consentaneously, survives even more rarely than the base form.

"The committee's verdict was entirely consentaneous with the wishes of the membership."
"The council's decision was consentaneous with the recommendations of its advisory panel."
"Their tastes proved so consentaneous that planning the trip required almost no discussion."
This rare 17th-century word is a cousin of 'spontaneous' — both end in the same Latin suffix '-aneous', but only one made it into everyday English.

Etymology of consentaneous
Consentaneous comes from the Latin consentaneus, meaning agreeing or accordant, derived from consentire, 'to feel together' — the same verb that gives us 'consent' and 'consensus'. The word entered English in the early seventeenth century, joining a family of Latinate adjectives ending in '-aneous' such as 'spontaneous' and 'instantaneous'. Its deeper root is the Latin verb sentire, 'to sense or feel', which also produced 'sentient', 'sentiment', 'assent', and 'dissent'. Though once used in legal and religious prose, it has largely fallen out of ordinary use.
