Etymology

It is inherited from Middle English stelthe, also stalthe,[2][3][4] probably inherited from Old English *stǣlþ, a form not recorded in Old English.[2][3][5][6][7] The OED takes the changing vowel as the sign of this Old English form, from Proto-Germanic *stēliþō, built on an ablaut variant of the root of steal (Old English stelan) with the abstract-noun suffix -th.[2][3][4] Etymonline compares health from heal and wealth from weal.[3] Old English had the related noun stælþing (“theft”),[8][9] and Old Norse stulþr (“theft”) and the English stouth come from the weak grade of the same root.[2][3] Orel thinks the verb Proto-Germanic *stelaną probably related to a root meaning "to stretch", hence "to cover".[10]

Earliest recorded meaning

Theft, the action of stealing: in the Middle English Genesis and Exodus, written about 1250 (manuscript before 1325);[2][3][4] the OED's first quotation overall is from Robert of Gloucester's Chronicle (1297), for furtive, underhand action.[2]

Semantic evolution

The word first meant theft, and kept that meaning into the 18th century; the OED's last quotation for it is from 1781.[2][3] Johnson (1755) still listed "the act of stealing; theft" first.[11] From the beginning it also meant secret or underhand action (1297), and Etymonline dates "secret action, clandestine method" to about 1300; this became the main sense.[2][3] The phrase by stealth is recorded from Gower's Confessio Amantis (1390).[2] Other senses did not last: a stolen thing or plunder (1426–1663) and plagiarism (1568–1659).[2][7] From Shakespeare's A Midsummer Night's Dream (1600) stealth was also the act of going furtively in or out of a place.[2][12] The Shorter Oxford notes that the word was rare in the 19th century except in by stealth.[7] Its modern revival came from military aircraft: the OED records stealth for stealth technology or a stealth bomber from 1979,[2] and Etymonline connects the boost with the radar-evading American stealth fighter and bomber.[3] Merriam-Webster dates the adjectival use, intended not to attract attention, to 1987.[12] In American campus slang of the 1990s stealth meant clever, tricky or sneaky.[13]
