sputnik: [20] Russian sputnik means literally ‘travelling companion’ (it is formed from s ‘with’ and put ‘way, journey’, with the agent suffix -nik). The Soviets gave the name to the series of Earth-orbiting satellites that they launched between 1957 and 1961. The first bleeps from space in October 1957 came as a severe shock to the West, which had not thought Soviet science capable of such a thing, and immediately propelled sputnik into the English language (the politically charged English version ‘fellow traveller’, which is more strictly a translation of Russian popútchik, was tried for a time, but never caught on).

It became one of the ‘in’ words of the late 1950s, and did much to popularize the suffix -nik in English (as in beatnik and peacenik).

his (pron.)youdaoicibaDictYouDict
Old English his (genitive of he), from Proto-Germanic *hisa (cognates: Gothic is, German es). Originally also the neuter possessive pronoun, but replaced in that sense c. 1600 by its. In Middle English, hisis was tried for the absolute pronoun (compare her/hers), but it failed to stick. For dialectal his'n, see her.
