In British Faërie there figures prominently a certain "Man in the Oak": according to Keightley, Puck, _alias_ Robin Goodfellow, was known as this "Man in the Oak," and he considers that the word _pixy_ "is evidently Pucksy, the endearing diminutive _sy_ being added to Puck like Bet_sy_, Nan_cy_, Dix_ie_".[255] It is probable that this adjectival _si_ recurring in _sw_eet, _so_oth, _su_ave, _sw_an, etc., may be equated with the Sanscrit _su_, which, as in _sw_astika, is a synonym for the Greek _eu_, meaning soft, gentle, pleasing, and propitious. When used as an affix, this "endearing diminutive" yields _spook_, which was seemingly once "dear little Pook," or "soft, gentle, pleasing, and propitious Puck". In Wales the fairies were known as "Mothers' Blessings," and although spook now carries a sinister sense, there is no more reason to suppose that "dear little Pook" was primarily malignant than to suggest that the Holy _Ghost_ was--in the modern sense--essentially _ghastly_. Skeat suggests that _ghost_ (of uncertain origin) "is perhaps allied to Icelandic _geisa_, to rage like fire, and to Gothic _us-gais-yan_, to terrify". Some may be aghast at this suggestion, others, who cannot conceive the Supreme Sprite except as a raging and consuming fury, will commend it. In the preceding chapter I suggested that the elementary derivation of ghost was _'goes_, the Great Life or Essence, and as _te_ in Celtic meant good, it may be permissible to modernise _ghoste_, also _Kostey_ of the egg, into _great life good_. That there was a good and a bad Puck is to be inferred from the West of England belief in Bucca Gwidden, the white or good spirit, and Bucca Dhu, the black, malevolent one.[256] Puck, like Dan Cupid, figures in popular estimation as a _pawky_ little pickle; in Brittany the dolmens are known as _poukelays_ or Puck stones, and the particular haunts of Puck were heaths and desert places. The place-name Picktree suggests one of Puck's sacred oaks; Pickthorne was presumably one of Puck's hawthorns, and the various Pickwells, Pickhills, Pickmeres, etc., were once, in all probability, _spook_-haunted. The highest point at Peckham, near London, is Honor Oak or One Tree Hill, and Peckhams or Puckhomes are plentiful in the South of England. One of them was inferentially near Ockham, at Great and Little Bookham, where the common or forest consists practically solely of the three pre-eminently fairy-trees--oak, hawthorne, and holly. The summit of the Buckland Hills, above Mickleham, is the celebrated, box-planted Boxhill, and at its foot runs Pixham or Pixholme Lane. On the height, nearly opposite Pixham Lane, the Ordnance Map marks Pigdon, but the roadway from Bookham to Boxhill is known, not as Pigdon Hill, but Bagden Hill. In all probability the terms Pigdon and Bagden are the original British forms of the more modern Pixham and Bok's Hill.
