Wiver is an outdated spelling of the word wyvern, which means a mythical two-legged dragon with wings. The IPA phonetic transcription of wyvern is /ˈwaɪvərn/. The "y" represents the sound /aɪ/ as in "eye," the "v" is pronounced as /v/, and the final "n" is /n/. The word is derived from the Old French word "wivre," which means a serpent, and it was later Anglicized as wyvern. Nowadays, it is commonly used in fantasy literature and gaming contexts.
The word wiver is a variant spelling of the word wyvern. Both wiver and wyvern refer to a mythical creature resembling a dragon. The etymology of the word wyvern can be traced back to old English and originates from the Old French word wivre or guivre. In turn, the Old French word can be traced back to the Latin word vipera which means viper or snake. The concept of the wyvern first appeared in European mythology and heraldry, and it often featured a dragon-like creature with wings, two legs, and a distinctive serpent-like tail. Therefore, the etymology suggests that over time, the word wiver became an alternative spelling of wyvern.
