Overview
The wyvern ( , sometimes spelled wivern) is a type of mythical dragon with two legs, two wings, and often a pointed tail which is said to be a venomous stinger.
The wyvern in its various forms is important in heraldry, frequently appearing as a mascot of schools and athletic teams (chiefly in the United States, United Kingdom, and Canada). It is a popular creature in European literature, mythology, and folklore. Today, it is often used in fantasy literature and video games. The wyvern in heraldry and folklore is rarely fire-breathing, unlike other dragons.
Etymology
According to the Oxford English Dictionary, the word is a development of Middle English wyver (attested fourteenth century), from Anglo-French wivre (cf. French guivre and vouivre), which originate from Latin vīpera, meaning "viper", "adder", or "asp". The concluding "–n" had been added by the beginning of the 17th century, when John Guillim in 1610 describes the "wiverne" as a creature that "partake[s] of a Fowle in the Wings and Legs ... and doth resemble a Serpent in the Taile". John Gibbon in 1682 emphasises that it "hath but two Legs".
Conversely, medievalist William Sayers proposes a more complex origin for the term. He notes that the Anglo-French guivre and its Middle English derivative ceased to retain the original sense of "venomous snake" after the Latin term was re-introduced into medieval Latin, freeing them up to take an alternative meaning. Adducing another meaning of wiver (this time Old English) and guivre, "light javelin", and noting partial resemblances between the size and shape of javelins and snakes, plus the later medieval era's increasing use of heavy armor and decreasing use of light javelins, he proposes that the concepts of "venomous snake" and "light javelin" were melded to produce a new term for a previously unimagined concept of flying snake, a kind of dragon.
