Etymology: "Vectorial" is a straightforward formation: it takes the noun "vector" and adds the adjectival suffix "-ial", meaning "of or relating to." A vector, in its oldest sense, is a carrier or conveyor, and the noun came into English from Latin "vector," meaning one who carries or conducts, derived from "vehere," "to carry." The mathematical and physical senses of the noun, a quantity with both magnitude and direction, developed much later and gave the adjective its current meaning of having a direction. The suffix has a longer ancestry than the noun. "-ial" descends from Latin "-ālis," which passed through Old French "-ial" before reaching Middle English, so the ending entered English by a well-worn route used by many adjectives such as "industrial" and "commercial." Pairing it with a Latin-derived noun is an ordinary English habit, which is why "vectorial" reads as a technical coinage built from parts that were already in place.
