in-

prefix meaning "not, opposite of, without" (also im-, il-, ir- by assimilation of -n- with following consonant), from Latin in- "not," cognate with Greek an-, Old English un-, from PIE *ne "not" (see un-(1)).

element meaning "into, in, on, upon" (also im-, il-, ir- by assimilation of -n- with following consonant), from Latin in- "in" (see in). In Old French this often became en-, which usually was respelled in English to conform with Latin, but not always, which accounts for pairs like enquire/inquire. There was a native form, which in West Saxon usually appeared as on- (as in Old English onliehtan "to enlighten"), and some verbs survived into Middle English (such as inwrite "to inscribe"), but all now seem to be extinct. Not related to in-(1) "not," which also was a common prefix in Latin: to the Romans impressus could mean "pressed" or "unpressed."

in- /ɪn/ prefix¹ (combining form).

ORIGIN: from in adverb, in preposition & (later) in adjective.

Also in other (Old English & later) formations with the sense ‘in, within, internal’, as inborn, inland; inpatient; with the sense of in adjective 2, as in-group, in-joke.

2.Prepositional phrs. composed of in preposition + noun give rise to (usu. hyphenated) attrib. adjectives, as in-calf, in-car.

3.Geometry. Repr. inscribed, as incentre, in-circle.
