Etymology 1

edit

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

Prefix

edit

in-

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

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

      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-].
