Word Origin & History

bur
"prickly seed vessel of some plants," c.1300, burre, from a Scandinavian source (cf. Dan. borre, Swed. hard-borre, O.N. burst "bristle"), from PIE *bhars- (see bristle). Transferred 1610s to "rough edge on metal," which may have been the source of the sense "rough sound
EXPAND
of the letter -r-" (see burr).

burr
"rough sound of the letter -r-" (especially that common in Northumberland), 1760, later extended to "northern accented speech" in general. Possibly the sound of the word is imitative of the speech peculiarity itself, or it was adapted from one of the senses of bur (q.v.), perhaps
from the phrase to have a bur in (one's) throat (late 14c.), which was a figure of speech for "feel a choking sensation, huskiness." The Scottish -r- is a lingual trill, not a true burr.
