The prefix eb- is being introduced as a new prefix for the English language, produced here for the first time of which I am aware. This prefix is underived from an existing language, and is a product of pure innovation, though it is intended to complement certain Latin prefixes that have been adopted into English. Eb- is a corollary of ob- and sub-, and has been introduced so as to allow a distinction to be made between what has otherwise been considered two forms of objectivity, in contrast to subjectivity. The first, which will continue to be used in the manner of objective, refers to epistemological outlooks that prefer dealing with objects. This includes common sense or direct-realist elements as well as indirect realist outlooks like empiricism. The second refers to what may otherwise be referred to as formal objectivity, but which I am deeming here ebjectivity, which refers instead to the objects of thought, typically as are employed in processes of deduction and abduction. Whereas a subject refers to an individual and their emotions and an object refers to arranged matter, an ebject refers instead to the ratio and proportion that results from a logically necessary interrelationship. For instance, price, in a mathematical modeling of economy, is ebjective, formerly considered to be some subset of objective. As objective tends to correspond to realism, induction, and empiricism, and subjective to matters unrelated to observation or reasoning, and to idealism, ebjective tends instead to correspond to optimism, deduction, and rationalism, including to the degree employed in common sense, pragmatism, and rational idealism. Whereas sub- refers to something under or outside of, and ob- to something over or against, eb- shall refer to a proportional ratio.
