Meanings

  • Primary meaning as a material: lumber or timber used in building, carpentry, and manufacturing
  • Industrial and technical contexts often refer to 木材 as raw wood material rather than finished wood
  • The term is distinct from 木 (wood in a living or general sense) and from 材木, another common term for timber

Etymology

(ki, tree/wood) + (zai, material; lumber) combine to form 木材, a native Japanese compound meaning timber or lumber; there is no foreign loanword involved.

Composition

  • 木: tree/wood—the core semantic field of the word
  • 材: material; timber; the second element specifying the kind of material

Usage

Used in formal, technical, and commercial contexts to refer to the wood material in construction, manufacturing, and supply chain discussions; in casual speech, 木材 is less common and speakers may say 木 or 材木 depending on emphasis.
💡 Tips
Mnemonic: visualize the tree 木 as the source and 材 as the material; together they form 木材, the material derived from a tree used in construction.

Variations

  • 材木 (zaimoku) — lumber, timber; common in construction contexts
  • 木質材料 (mokushitsu zairyō) — wood-based material; more technical
