not tissue
Etymology
'non-tissue' originates from Modern English, specifically the prefix 'non-' (ultimately from Latin 'non') meaning 'not', combined with the word 'tissue' (from Old French 'tissu').
'tissue' passed into English from Old French 'tissu' (past participle of 'tistre'/related to 'tisser'), ultimately from Latin 'texere' meaning 'to weave'. The compound 'non-tissue' is a modern English formation using the negative prefix 'non-' plus 'tissue' to indicate 'not tissue'.
Originally, 'tissue' referred to something woven (a web or fabric); over time it came to mean a connected structure in animals and plants (biological tissue). 'Non-tissue' simply negates that modern sense to denote materials or items that are not biological tissue.
