Beggars Burn 1856 OS 6 inch 1st edn [flowing through Glassert Den]
Glassart Burn 1888 x 1914 OS 6 inch 1st revision
en Glassart + Sc burn
Glassart appears so late in the record that any etymology must be tentative; it may derive from G glas + G à(i)rd ‘green height’, with reference to the good upland grazing through which the burn flows on the southern slopes of the Ochils. However, two other burn-names, whose modern forms closely resemble Glassart, viz the Glazert Burn in Cunningham AYR and the Glazert Water, Campsie STL, have earlier forms which indicate that the second element is either G dobhar or British (or in the case of Glassart, Pictish) *duvr or similar, meaning ‘water’, the first element presumably being British (or Pictish) *glas ‘green’. A third possibility is that Glassart derives from G glais àrd ‘high burn’, with the expected stress on the second syllable moved to the first because of its frequent combination with a following element such as burn or den.
On OS 6 inch 1st edn (1856) Beggars Burn is the name of the burn as it flows past Newhill Cottage and The Howe, forming the boundary with ANY and what is now NBH (formerly ANY FIF), until it turns south and becomes the Auchtermuchty Burn (see OS Name Book 50, 26). The 1856 map also shows Glassert (sic) Den at around NO229133, as the den through which the Beggars Burn flows before it turns south. In later OS 6 inch maps, the upper reaches of the burn are still called Beggars Burn (1888 × 1914, 1st revision and thereafter, including 2006 edition of 1:10,000 map), while the lower reaches at Glassart Den are called Glassart Burn.
The Forestry Commission refers to a nearby wood as Glassart Wood (NO229132), while the area around the wood, the burn and the den is known locally as The Glassarts.
