gnarled: [17] Gnarled is essentially a 19thcentury word. It is recorded once before then, in Shakespeare’s Measure for Measure 1603 (‘Thy sharp and sulphurous bolt splits the unwedgable and gnarled oak’), but its modern currency is due to its adoption by early 19th-century romantic writers. It is probably a variant of knurled [17], itself a derivative of knur or knor ‘rough misshapen lump, as on a tree trunk’ [14], which is related to German knorren ‘knot, gnarled branch or trunk’.

gnarled (adj.)youdaoicibaDictYouDict
c. 1600, probably a variant of knurled, from Middle English knar "knob, knot in wood" (late 14c.), earlier "a crag, twisted rock" (early 13c.), from a general group of Germanic words that includes English knob, knock, knuckle, knoll, knurl. Gnarl (v.) "make knotty," gnarl (n.) "a knotty growth on wood," and gnarly (adj.) all seem to owe their existence in modern English to Shakespeare's use of gnarled in 1603:
Thy sharpe and sulpherous bolt Splits the vn-wedgable and gnarled Oke. ["Measure for Measure," II.ii.116]
"(Gnarled) occurs in one passage of Shakes. (for which the sole authority is the folio of 1623), whence it came into general use in the nineteenth century" [OED].
