The etymology of the name Loki has yet to be solved. It may be related to Old Norse luka, meaning "close" but Sanskrit explains 'Lo-k yksd(yksdh) meaning "to shine", 'i' is used for feminine the 'Lightning' goddess.
Loki is alternately referred to as Loptr, which is generally considered derived from Old Norse lopt meaning "air", and therefore points to an association with the air. Sanskrit Lop yksi means "deprivation, violation, transgression, dropping" an action of lightning. The name Hveðrungr (Old Norse '? one who roars') is also used in reference to Loki, occurring in names for Hel.
The völur were referred to by many names. The Old Norse word volva means "wand carrier" or "carrier of a magic staff", and it continues Proto Germanic *walwon, which is derived from a word for "wand" (Old Norse volr). Vala, on the other hand, is a literary form based on Völva.
Sanskrit Vyal O;ky means "cruel, fierce, savage, a tiger, hurt, a snake, swift fire, tremulous" later this word was used as 'violence in European languages. Being corrupt, the word became Vyal > Vyol > Vol and suffix rh j% jk or Va o% ok means "speed, fire" and "move, strike, go, shake" respectively.
