Etymology

It is inherited from Middle English naddre (“snake”), later addre and eddre,[2][3] inherited from Old English nǣdre (“snake, serpent”), also næddre,[4][5][6][7] from Proto-Germanic *nadrǭ,[8][9] and it lost its first letter when a naddre was taken for an addre.[10][3][6][7][11] Barnhart places the change between about 1300 and 1400, and Etymonline between the 14th and 16th centuries;[10][4] apron, auger and umpire lost an n- in the same way.[6][7][4] The word has cognates in Middle Dutch nadre, Old Saxon nādra and Old High German nātara, whence German Natter,[12][6][7] and with a different ablaut grade in Old Norse naðra and Gothic 𐌽𐌰𐌳𐍂𐍃 (nadrs).[12][6] According to the OED, Dutch adder and Middle Low German adder dropped the n- by a similar reanalysis after the indefinite article.[12] Outside Germanic, the word is related to Latin natrīx (“water snake”), whose sense was probably influenced by natō (“to swim”), and to Old Irish nathir (“snake”) and Welsh neidr (“snake”).[12][4][13][3] Etymonline starts from Proto-Indo-European *nētr- (“snake”),[4] which Merriam-Webster writes *nh₁tr- and takes as probably an agent noun meaning "one who winds or twists", from *(s)neh₁- (“to twist together, spin”),[3] the base the OED and Klein also propose, and the source of needle.[12][7]

Earliest recorded meaning

A snake or serpent of any kind, especially the serpent of the Fall: early Old English, in the Royal Psalter.[12][4] Barnhart dates the Old English form to about 950, and Dictionary.com to before 950.[10][14] Bosworth–Toller glosses it as any kind of serpent, adder or viper.[5]

Semantic evolution

The word was general at first, as Ayto stresses: any snake, not just the adder.[11] The generic use lasted until 1846 in the OED's record, while from Old English on the word was also the name of the common viper,[12] and Etymonline regards it as restricted to that animal since Middle English, the viper being the only venomous reptile in Britain.[4] The figurative use for a treacherous or malicious person is also Old English and follows the same use of Latin words for snakes in the Vulgate;[12] a further sense, a winged serpent or dragon, died out by 1500.[12] In Gower the spellings addre, eddre, neddre and thaddre stand side by side, while Chaucer has forms with n-,[15] and Ayto notes that nadder had left the mainstream language by the 17th century,[11] though nedder lived on in northern English dialect.[4][16] English speakers then applied the word to venomous snakes abroad from 1698, as in puff adder, and in the United States from 1842 to harmless snakes such as the hognose.[12][4] Johnson (1755) noted that adders and snakes were not the same in common language.[17] In Shropshire dialect it could still mean any snake,[18] regional English also used it for the slow-worm, once thought venomous,[12] and northern English for a dragonfly.[12] The image of the deaf adder goes back to Psalm 58, where the snake stops its ears against the charmer.[4]
