From Latin in-, a prefixation of in (“in, into”), ultimately from Proto-Indo-European *h₁én.

in-

1. (forms verbs) used to denote derivation
2. (obsolete, rare) used as an intensifier

• The prefix is used together with a verbal ending suffix to derive causative verbs from adjectives or nouns:

Examples:

‎in- + ‎arido (“dry”, “arid”) → ‎inaridire (“to parch”, “to dry up”)

‎in- + ‎fiamma (“flame”) → ‎infiammare (“to enflame”, “to kindle”)

• When used with verbs, it's usually a reflection of derivation in Latin, and retains the original meaning of “into”, “inside”:

Example:

‎in- + ‎fondere → ‎infondere (“to infuse”, “to instill”) (cfr. Latin īnfundere)

• In some cases, the meaning of “into” can also be found in verbs of modern derivation:

Example:

‎in- + ‎carcere (“jail”, “prison”) → ‎incarcerare (“to imprison”, “to incarcerate”)

From Latin in- (“un-, not”), from Proto-Indo-European *n̥-, zero grade form of the sentence negative *ne.

in-

1. used to denote negation or opposition or privation; un-; in-; a-

• The suffix is usually found in adjectives (and nouns therefrom derived):

Examples:

‎in- + ‎abile (“able”, “capable”) → ‎inabile (“unable”, “incapable”)

‎in- + ‎felice (“happy”) → ‎infelice (“unhappy”)

‎in- + ‎desiderabile (“desirable; advisable”) → ‎indesiderabile (“undesirable, unwelcome”)

• More rarely, it is found in adjectives derived from nouns:

Example:

‎in- + ‎colore (“colour/color”) → ‎incolore (“uncoloured/uncolored”)

• ni, nì

• (Classical) IPA^(key): /in/, [ɪn]
• (modern Italianate Ecclesiastical) IPA^(key): /in/, [in]

From Proto-Italic *ən-, from Proto-Indo-European *n̥- (“not”), zero-grade form of the negative particle *ne (“not”). Akin to ne-, nē, nī.[1]

in-

1. un-, non-, not

Affixed primarily to adjectives.

The pronunciation or spelling of the prefix may be changed in some situations:

• Before b, p or m, it may become im-. The spelling in- is also found in this context.

  ‎in- + ‎barba (“beard”) → ‎imberbis (“beardless”) or inberbis.

  ‎in- + ‎patiēns (“patient”) → ‎impatiēns (“impatient”) or inpatiēns.

  ‎in- + ‎mātūrus (“mature”) → ‎immātūrus (“immature”) or inmātūrus.

• Before l or r, it may become il- or ir-, respectively. These assimilations only became usual in post-Augustan Latin: until a late date, the usual Roman spellings were inl- and inr-.[2]

  ‎in- + ‎labōrātus (“worked, toilsome”) → ‎illabōrātus (“unworked, uncultivated”) (post-Augustan) or inlabōrātus.

  ‎in- + ‎reverēns (“reverent”) → ‎irreverēns (“irreverent”) (post-Augustan) or inreverēns.

• Before gn and sometimes n, it becomes ig- (pronounced [ɪŋ-]).

  ‎in- + ‎gnārus (“knowlegable”) → ‎ignārus (“ignorant”)

  ‎in- + ‎nōmen (“name”) → ‎ignōminia (“dishonor”)

• Before f or s, it becomes īn- (pronounced [ĩː-]).

  ‎in- + ‎fīnītus (“finite”) → ‎īnfīnītus (“endless, infinite”)

  ‎in- + ‎sānus (“healthy, sane”) → ‎īnsānus (“mad, insane”)

• Before g, c or q, the spelling remains in-, but the pronunciation becomes [ɪŋ-].
