variant the in- prior to -b-, -m-, -p- in the feeling of "not, the contrary of" (immobile, impersonal; see in- (2)) as well as "in, into" (implant, impoverish; check out in- (1)). In part English words it alternates with em- (1).

element definition "into, in, on, upon" (also im-, il-, ir- by assimilation of -n- with complying with consonant), native Latin in- "in," from PIE source *en "in."

In Old French (and hence in middle English) this often ended up being en-, i beg your pardon in English had a strong tendency to revert to Latin in-, yet not always, i beg your pardon accounts because that pairs such as enquire/inquire. There was a indigenous form, i beg your pardon in West Saxon usually showed up as on- (as in Old English onliehtan "to enlighten"), and some of those verbs survived into Middle English (such as inwrite "to inscribe"), but all now seem to it is in extinct.

Not pertained to in- (1) "not," which likewise was a usual prefix in Latin, leading to confusion: to the Romans impressus can mean "pressed" or "unpressed;" inaudire supposed "to hear," but inauditus intended "unheard of;" in so late Latin investigabilis can mean "that may be searched into" or "that can not be searched into." Latin invocatus to be "uncalled, uninvited," yet invocare was "to call, very nice one to."

The problem has ongoing in English; the uncertainty over what is expected by inflammable being a generally cited example. Implume (1610s) expected "to feather," yet implumed (c. 1600) supposed "unfeathered." Impliable deserve to mean "capable of gift implied" (1865) or "inflexible" (1734). Impartible in 17c. Can mean "incapable of gift divided" or "capable of being imparted." Impassionate can be "free indigenous passion" or it have the right to mean "strongly stirred through passion." inanimate (adj.) is "lifeless," yet Donne offers inanimate (v.) to typical "infuse through life or vigor." Irruption is "a break in," but irruptible is "unbreakable."

In addition to boost "use come one's profit," center English likewise had a verb improve an interpretation "to disprove" (15c.). To inculpate is "to accuse," but inculpable way "not culpable, cost-free from blame." Infestive has actually meant "troublesome, annoying" (1560s, from infest) and "not festive" (1620s). In center English inflexible could mean "incapable of being bent" or "capable of gift swayed or moved." In 17c., informed could mean "current in information," formed, animated," or "unformed, formless" ("This to be an aer use" ). Inhabited has meant "dwelt in" (1560s) and also "uninhabited" (1610s); inhabitable an in similar way has been offered on the contrary senses, a man that goes back to so late Latin.
