The modern Welsh name for fairies is y Tylwyth Teg, the fair folk or family. This is sometimes lengthened into y Tylwyth Teg yn y Coed, the fair family in the wood, or Tylwyth Teg y Mwn, the fair folk of the mine. They are seen dancing in moonlight nights on the velvety grass, clad in airy and flowing robes of blue, green, white, or scarlet--details as to colour not usually met, I think, in accounts of fairies. They are spoken of as bestowing blessings on those mortals whom they select to be thus favoured; and again are called Bendith y Mamau, or their mother's blessing, that is to say, good little children whom it is a pleasure to know. To name the fairies by a harsh epithet is to invoke their anger; to speak of them in flattering phrase is to propitiate their good offices. The student of fairy mythology perceives in this propitiatory mode of speech a fact of wide significance. It can be traced in numberless lands, and back to the beginning of human history, among the cloud-hung peaks of Central Asia. The Greeks spoke of the furies as the Eumenides, or gracious ones; Highlanders mentioned by Sir Walter Scott uncover to the gibbet and call it 'the kind gallows;' the Dayak will not name the small-pox, but calls it 'the chief;' the Laplander calls the bear 'the old man with the fur coat;' in Ammam the tiger is called 'grandfather;' and it is thought that the maxim, 'Speak only good of the dead,' came originally from the notion of propitiating the ghost of the departed,[9] who, in laying off this mortal garb, had become endowed with new powers of harming his late acquaintance.

The Ellyllon are the pigmy elves who haunt the groves and valleys, and correspond pretty closely with the English elves. The English name was probably derived from the Welsh _el_, a spirit, _elf_, an element; there is a whole brood of words of this class in the Welsh language, expressing every variety of flowing, gliding, spirituality, devilry, angelhood, and goblinism. Ellyllon (the plural of ellyll), is also doubtless allied with the Hebrew Elilim, having with it an identity both of origin and meaning.[10] The poet Davydd ab Gwilym, in a humorous account of his troubles in a mist, in the year 1340, says: Yr ydoedd ym mhob gobant Ellyllon mingeimion gant. There was in every hollow A hundred wrymouthed elves.
