Common collocations

  • piece of burl
  • slab of burl

  • veneer

    a thin decorative layer of wood; 'veneer' is a broader term that includes non-burl materials, while 'burl' specifically comes from a tree outgrowth.

  • burlywood

    a less common name for the same material; 'burl' is the usual term in woodworking.

Grammar Patterns

burl + as + material

burl veneer + on + [object]

Usage Note

This sense refers to the material itself, not to the tree growth — contrast with sense 1, which describes the physical outgrowth on a tree. Burl veneer is typically very thin (less than 3 mm) and glued onto a cheaper base wood.

Synonym discussion

Sense: noun/1

All four words describe parts of a tree, but they differ in what they refer to. A 'burl' is a rounded, hard growth on the outside of a trunk or branch, prized for its decorative internal grain. A 'knot' is a hard circular area inside the wood where a branch once connected to the trunk — it is visible only after the wood is cut and can be a defect or a feature. A 'gnarl' is a rough, twisted, often gnarled section of wood that may include multiple small growths; the word emphasises an irregular, contorted shape. 'Outgrowth' is the most general term: anything that grows outward from a tree, including burls, gnarls, new branches, and shoots. For example, a woodworker might say 'I turned this burl into a bowl' but 'the knot cracked when I drilled into it'.

Etymology

Late LatinOld FrenchMiddle EnglishEnglish

The word 'burl' comes from Middle English 'burle', meaning a tuft of wool or a knot in thread. It traces further back to Old French 'burle' (a tuft of wool) and ultimately to Late Latin 'burra', meaning coarse wool or flock of wool. The meaning shifted over time: first it described knots in wool and cloth, then expanded to include the knot-like growths on trees, and finally to the decorative wood obtained from those growths.
