star (n.)youdaoicibaDictYouDict[star 词源字典]
Old English steorra "star," from Proto-Germanic *sterron, *sternon (cognates: Old Saxon sterro, Old Frisian stera, Dutch ster, Old High German sterro, German Stern, Old Norse stjarna, Swedish stjerna, Danish stierne, Gothic stairno).

This is from PIE *ster- (2) "star" (cognates: Sanskrit star-, Hittite shittar, Greek aster, astron, Latin stella, Breton sterenn, Welsh seren "star"), of uncertain connection to other roots. Some suggest it is from a root meaning "to strew, scatter." Buck and others doubt the old suggestion that it is a borrowing from Akkadian istar "venus." The source of the common Balto-Slavic word for "star" (Lithuanian žvaigžde, Old Church Slavonic zvezda, Polish gwiazda, Russian zvezda) is not explained.

Astrological sense of "influence of planets and zodiac on human affairs" is recorded from mid-13c., hence "person's fate as figured in the stars" (c. 1600); star-crossed "ill-fated" is from "Romeo and Juliet" (1592). Meaning "lead performer" is from 1824; star turn is from 1898. Stars as a ranking of quality for hotels, restaurants, etc. are attested from 1886, originally in Baedecker guides. Sticker stars as rewards for good students are recorded from 1970s. Brass star as a police badge is recorded from 1859 (New York City). Star-cluster is from 1870. To see stars when one is hit hard on the head is from 1839.[star etymology, star origin, 英语词源]
