Etymology

The rough edge is a spelling variant of bur,[2][3][4][5] which is inherited from Middle English burre,[6][7] probably from a Scandinavian source.[8][2][9][4] Dictionaries compare Danish burre (“bur, burdock”) and Swedish kardborre (“burdock”),[9][4][7] Old Swedish borre (“bur”),[6] and Old Norse burst (“bristle”),[8][2] which is related to Old English byrst (“bristle”), the source of bristle.[8][2][6] Etymonline traces the group to Proto-Indo-European *bhars-.[8]

Earliest recorded meaning

As bur, the prickly seed case of a plant: about 1330 in the OED,[10] and probably before 1300, in Arthour and Merlin, in Barnhart.[2] The spelling burr for a rough edge left on metal is first recorded in 1611, in Florio's A World of Words.[2][10]

Semantic evolution

The seed head gave the figure of something that sticks and clings, such as a person hard to shake off (from 1590) and a bur in the throat (from 1393).[10][3] Etymonline sees the sense "rough edge on metal" (1610s) as a transfer from the prickly seed case.[8] The sense "a tool shaped like a bur" appeared in 1794,[2][10] and in the 19th century burr named a dentist's or surgeon's drill.[3] Dictionaries now prefer the spelling bur for the seed case and burr for the rough edge and the tool,[6][11] though Merriam-Webster also keeps bur for the dental drill bit.[12] The verbs, to form a burr on metal and to remove burrs from it, are recorded from the later 19th century.[10][13]

First attested
1760 Samuel Foote, The Minor

Etymology

The rough pronunciation of r is probably imitative,[2][4][15][14] though the OED and Barnhart think it was probably associated with the roughness of a bur, the prickly seed case.[14][2] Etymonline suggests it may come from the phrase a bur in one's throat, a choking or husky feeling, recorded from the late 14th century.[8][14]

Earliest recorded meaning

A rough sounding of the letter r, especially the uvular trill of Northumberland: 1760, in Samuel Foote's The Minor.[14][2][8]

Semantic evolution

By 1849, in C. Brontë's Shirley, it was used loosely of any rough or dialectal pronunciation,[14] and Etymonline notes its extension to northern speech in general.[8] The OED holds that the Scottish r, a trill made with the tongue, is not a true burr,[8] but the American Heritage Dictionary defines the burr as that trill, typical of Scottish speech, and Merriam-Webster gives both.[13][12] The Northumberland burr was sharply bounded, and in the 19th century it was said to have begun as a personal defect of Hotspur, imitated by his followers.[16] Since 1818, in Keats, a burr has also been a whirring sound.[14][4] The verb, to speak with a burr, is first recorded in 1798, in Wordsworth's The Idiot Boy.[14][2][6]

  • 1849 – loosely, a rough or dialectal pronunciation.[14]
