The word nwyfre is a Middle Welsh word meaning ‘sky’ or ‘vigor.’ In Irish and Scots Gaelic the word is “neart.” (NYart). In Wales the word was usually used to refer to a windy sky. The 19th century Druid Revivalist Iolo Morganwg popularized its use as a ‘magical’ word. He probably misunderstood the etymology of the word, which originally had no mystical connotation, but the word ‘nwyfre’ h as taken on a new meaning in some contemporary Druid circles. The way modern Druids use the word, it now means ‘life force’ or ‘life energy.’
