SURD,
inexpressible by a rational number
or having no rational root. (L.) Cotgrave translates nombre
sourd by 'a surd number.' A term in mathematics, equivalent to irrational,
in the math. sense.—Lat. surdus, deaf; hence, deaf to reason,
irrational. The word is frequently applied to colours, when it means
dim, indistinct, dull; thus surdus color = dim colour, Pliny, Nat. Hist.
b. xxxiii. c. 5. So likewise Lat. sordere = to be dirty;
allied to E. swart and swarthy; see Swart.
Der. surd, adj., irrational; absurd, q.v.
