in-1

1.
a prefix representing English in (income; indwelling; inland , etc.), but used also as a verb-formative with transitive, intensive, or sometimes little apparent force (intrust; inweave , etc.). It often assumes the same forms as in-2 , such as en-, em-, im-3 .
Origin
Middle English, Old English; see in

in-2

1.
a prefix of Latin origin meaning primarily “in,” but used also as a verb-formative with the same force as in-1. (incarcerate; incantation).
Also, il-, im-, ir-.
Compare em-, en-
Origin
< Latin, combining form of in (preposition); cognate with in

in-3

1.
a prefix of Latin origin, corresponding to English un-, having a negative or privative force, freely used as an English formative, especially of adjectives and their derivatives and of nouns (inattention; indefensible; inexpensive; inorganic; invariable). It assumes the same phonetic phases as in-2. (impartial; immeasurable; illiterate; irregular , etc.). In French, it became en- and thus occurs unfelt in such words as enemy (French ennemi, Latin inimicus, lit., not friendly).
Also, il-, im-, ir-.
Origin
< Latin; akin to an-1, a-6, un-1
Synonym Study
The prefixes in- and un- may both have, among other uses, a negative force. In- is the form derived from Latin, and is therefore used in learned words or in words derived from Latin or (rarely) Greek: inaccessible, inaccuracy, inadequate, etc. Un- is the native form going back to Old English, used in words of native origin, and sometimes used in combination with words of other origins if these words are in common use: unloving, ungodly, unfeeling, unnecessary, unsafe.

-in1

1.
a suffix, occurring in adjectives of Greek and Latin origin, meaning “pertaining to,” and (in nouns thence derived) also imitated in English (coffin; cousin , etc.).
Origin
Middle English -in, -ine < Old French < Latin -inus, -ina, -inum < Greek -inos, -inē, -inon

-in2

1.
a noun suffix used in a special manner in chemical and mineralogical nomenclature (glycerin; acetin , etc.). In spelling, usage wavers between -in and -ine. In chemistry a certain distinction of use is attempted, basic substances having the termination -ine rather than -in (aconitine; aniline , etc.), and -in being restricted to certain neutral compounds, glycerides, glucosides, and proteids (albumin; palmitin , etc.), but this distinction is not always observed.
Origin
< Neo-Latin -ina. See -ine2

-in3

1.
a suffixal use of the adverb in, extracted from sit-in, forming compound nouns, usually from verbs, referring to organized protests through or in support of the named activity (kneel-in; chain-in; be-in) or, more generally, to any organized social or cultural activity (cook-in; sing-in).

Word Origin and History for in

Old English in (prep.) "in, into, upon, on, at, among; about, during;" inne (adv.) "within, inside," from Proto-Germanic *in (cf. Old Frisian, Dutch, German, Gothic in, Old Norse i), from PIE *en "in" (cf. Greek en, Latin in "in, into," Old Irish in, Welsh yn-, Old Church Slavonic on-). As an adjective from 1590s.

The forms merged in Middle English. Modern sense distinction between in and on is from later Middle English. Sense of "holding power" (the in party) first recorded c.1600; that of "exclusive" (the in-crowd, an in-joke) is from 1907 (in-group); that of "stylish, fashionable" (the in thing) is from 1960. The noun sense of "influence, access" (have an in with) first recorded 1929 in American English. In-and-out "copulation" is attested from 1610s.

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- (cf. Old English onliehtan "to enlighten"), and some verbs survived into Middle English (cf. 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

suffix attached to a verb, first attested 1960 with sit-in (which probably was influenced by sit-down strike); used first of protests, extended c.1965 to any gathering.

chemical suffix, usually indicating a neutral substance, antibiotic, vitamin, or hormone; see -ine (2).
