nativize (v.)

late 14c., natif, "natural, inborn, hereditary, connected with something in a natural way," from Old French natif "native, born in; raw, unspoiled" (14c.) and directly from Latin nativus "innate, produced by birth," from natus, past participle of nasci (Old Latin gnasci) "be born," related to gignere "beget," from PIE root *gene- "give birth, beget," with derivatives referring to procreation and familial and tribal groups.

From early 15c. as "born in a particular place, of indigenous origin or growth, not exotic or foreign," also "of or pertaining to one by birth" (as in native land). Also used from early 15c. in a now-obsolete sense of "bound; born in servitude or serfdom." Of metals, minerals, etc., "occurring in a pure state in nature," 1690s.

Native American in reference to the aboriginal peoples of the Americas is attested by c. 1900 as the name of a journal "devoted to Indian education."

In the early 1970s, ... activist Indians began calling themselves Native Americans (from the peyote-using Native American Church, incorporated in 1918 in Oklahoma and subsequently in other states). The newer term, aside from disassociating its users from the reservation life of the past, was a form of one-upsmanship, since it reminded whites just who was on the premises first. [Hugh Rawson, "Wicked Words"]

word-forming element used to make verbs, Middle English -isen, from Old French -iser/-izer, from Late Latin -izare, from Greek -izein, a verb-forming element denoting the doing of the noun or adjective to which it is attached.

The variation of -ize and -ise began in Old French and Middle English, perhaps aided by a few words (such as surprise, see below) where the ending is French or Latin, not Greek. With the classical revival, English partially reverted to the correct Greek -z- spelling from late 16c. But the 1694 edition of the authoritative French Academy dictionary standardized the spellings as -s-, which influenced English.

In Britain, despite the opposition to it (at least formerly) of OED, Encyclopaedia Britannica, the Times of London, and Fowler, -ise remains dominant. Fowler thinks this is to avoid the difficulty of remembering the short list of common words not from Greek which must be spelled with an -s- (such as advertise, devise, surprise). American English has always favored -ize. The spelling variation involves about 200 English verbs.
