stealth

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]
