tissue: [14] Tissue is etymologically ‘woven’ cloth. The word was borrowed from Old French tissu ‘fine woven cloth’, which was a noun use of the past participle of tistre ‘weave’. This in turn was descended from Latin texere ‘weave’ (source of English text, texture, etc). The application of the word to ‘physiological substance’ dates from the early 19th century. The original notion of weaving is preserved metaphorically in expressions such as ‘tissue of lies’. => technical, text, texture, toilet
