Origin: A word inherited from Germanic.
Etymology: Cognate with Middle Dutch nader , nadre , nadder , adere , adder , etc. (Dutch adder ), Old Saxon nādra , nādāra (Middle Low German nāder , ader , adder ), Old High German nātra , nātāra (Middle High German nātere , nāter , German Natter (now chiefly in sense ‘grass snake’), also (originally regional) Otter viper), and (with different ablaut grade) Old Icelandic naðra , naðr , Gothic nadrs < the same Indo-European base as (with different ablaut grade and further suffix) classical Latin natrīx water snake (with sense influenced by natāre to swim: see natant adj.) and Early Irish nathir snake, probably ultimately < the same Indo-European base (originally with the sense ‘to twist, turn’) as e.g. classical Latin nēre to spin (see needle n.). In sense 1b after corresponding use of classical Latin serpēns serpent n. (in post-classical Latin in this sense (Vulgate)), vīpera viper n. (already in classical Latin in this sense). With sense 3 compare earlier adder fly n. at Compounds 2, adderbolt n.In Old English usually a weak feminine (nǣdre , næddre ); occasionally also attested as a strong masculine (compare Northumbrian genitive singular nedres ). Attested early in place names, as Nedrefelle , Sussex (1086; now Netherfield); compare also the following from 12th-cent. copies of Somerset charters of earlier date:lOE Bounds (Sawyer 254) in W. de G. Birch Cartularium Saxonicum (1885) I. 229 Swa to wiðig leagate, þæt to næddran beorge.lOE Bounds (Sawyer 511) in W. de G. Birch Cartularium Saxonicum (1887) II. 495 On sciteres flodan on nedder heal, of nedder heale on þære greatan bechan geat. The β. forms show metanalysis (see N n.). The forms without initial n- in Dutch, Middle Low German, and German similarly result from reanalysis in contexts where the indefinite article (in -n) immediately preceded the word.
1.
a. In generic sense: a snake, a serpent, esp. with reference to the serpent as a manifestation of the devil in the biblical account of the Fall in the Garden of Eden; (hence, by extension) the devil. Also: a representation of a snake or serpent. Obsolete. old adder: the devil (see old serpent at old adj. 14).
