wood pulp

Synonym discussion
Sense: noun/1
All three terms relate to the same industrial material, but they differ in scope. 'Wood pulp' specifies the source (wood) and the processed state (fibrous, wet mass used as a raw material). 'Pulp' is the broadest term: it can refer to the soft, wet mass of crushed fruit (orange pulp), vegetables, or any organic matter — not just wood. 'Paper pulp' is nearly synonymous with wood pulp but technically includes fibres from other sources such as cotton, hemp, or bamboo. 'Cellulose' is not a synonym in usage — it refers to the chemical compound (a polysaccharide) that makes up plant fibres, not the wet industrial material. For example: 'This mill produces wood pulp for newsprint' sounds natural; 'This mill produces cellulose for newsprint' sounds unnatural because cellulose is a component, not the bulk material. When shopping for paper products, look for 'made from wood pulp' or 'wood-pulp-based'; 'cellulose' on an ingredient list usually indicates a food additive, not paper.
Common collocations
Etymology
The compound 'wood pulp' combines 'wood' (from Old English 'wudu', meaning forest or trees) with 'pulp' (from Latin 'pulpa', meaning the fleshy, soft part of fruit or animal tissue). The term entered industrial use in the mid-19th century, when mechanical and chemical processes were invented to grind whole logs into a fibrous mush for papermaking. Before this period, paper was made almost entirely from rags and cotton fibres.
