Tissue


Definition:

  • (n.) A woven fabric.
  • (n.) A fine transparent silk stuff, used for veils, etc.; specifically, cloth interwoven with gold or silver threads, or embossed with figures.
  • (n.) One of the elementary materials or fibres, having a uniform structure and a specialized function, of which ordinary animals and plants are composed; a texture; as, epithelial tissue; connective tissue.
  • (n.) Fig.: Web; texture; complicated fabrication; connected series; as, a tissue of forgeries, or of falsehood.
  • (v. t.) To form tissue of; to interweave.
