intersubjective adj.

word-forming element used freely in English, "between, among, during," from Latin inter (prep., adv.) "among, between, betwixt, in the midst of" (also used extensively as a prefix), from PIE *enter "between, among" (source also of Sanskrit antar, Old Persian antar "among, between," Greek entera (plural) "intestines," Old Irish eter, Old Welsh ithr "among, between," Gothic undar, Old English under "under"), a comparative of root *en "in."

A living prefix in English from 15c. and used with Germanic as well as Latinate words. Spelled entre- in French; most words borrowed into English in that form were re-spelled 16c. to conform with Latin except entertain, enterprise. In Latin, spelling shifted to intel- before -l-, hence intelligence, etc.

c. 1500, "characteristic of one who is submissive or obedient," from Late Latin subiectivus "of the subject, subjective," from subiectus "lying under, below, near bordering on," figuratively "subjected, subdued"(see subject (n.)). In early Modern English as "existing, real;" more restricted meaning "existing in the mind" (the mind as "the thinking subject") is from 1707, popularized by Kant and his contemporaries; thus, in art and literature, "personal, idiosyncratic" (1767). Related: Subjectively; subjectiveness.
