[1]              Sandahl 1951 pp. 106-107. Sandahl gives the example of the Scottish form raughter (rauchter, rawchter) for rafter, which is thought to be from LG rachter (< rafter). The occurence of thocht in a region where otherwise thaft is the dominating form, points to a development which must have taken place independently from the south of England, where the same change of [f] > [x] must have occured, as the dominating form in southern England is thought (cf. a map of Elmer (Elmer 1973, p. 107) which shows a clear distribution of thoft and thought, with thoft being used north of a line running approximately from the Severn to the Wash, and thought south of it).
