If Watson is correct (1926, 250–1), the first element is G lann, ‘an enclosure or field’ and the second element, annet, is from G annaid, which Clancy (1995) has shown means something like ‘mother-church’. However, the earliest form cited above, Langannand, makes a derivation from annaid problematic, while the first element lang could be Sc lang ‘long’.
It exists today as the name of the coal-fired power-station and the recently closed coal-mine; also in the coastal feature Longannet Point NS946852. But the OSA Perth citation mentioned above speaks of the quarry’s product: ‘a durable stone, perfectly white, of a small greek [‘grain or texture’], and takes on a fine smooth polish’, indicating quite different mining activities in the eighteenth century.
OS Pathf. Longannet Point is on the coast at NS946852. The rock of Longannet is probably the rock exposed at low tide shown on OS 1 inch 7th Series (1960) a short distance east of Longannet Point.
