French researcher Victor T. Junod was the first to describe symptoms of narcosis in 1834, noting the functions of the brain are activated, imagination is lively, thoughts have a peculiar charm and, in some persons, symptoms of intoxication are present.
The word green comes from the Middle English and Old English word grene, which, like the German word grÃ¼n, has the same root as the words grass and grow. It is from a Common Germanic *gronja-, which is also reflected in Old Norse grÃ¦nn, Old High German gruoni (but unattested in East Germanic), ultimately from a PIE root * ghre-to grow, and root-cognate with grass and to grow.
In the comparative study of color terms in the world's languages, green is only found as a separate category in languages with the fully developed range of six colors (white, black, red, green, yellow, and blue), or more rarely in systems with five colors (white, red, yellow, green, and black/blue).
