Synonym discussion

Sense: noun/1

All four words refer to what something is physically made of, but they differ in register and precision. 'Stuff' is the most informal and vague — you use it when you do not know or care about the exact name ('What is that gooey stuff on the table?'). 'Substance' is more scientific or formal; it implies a material with a known chemical composition or consistent properties ('a sticky substance', 'a toxic substance'). 'Material' focuses on what something is made from or what can be created with it — it often implies a purpose ('building materials', 'raw materials'). 'Matter' is the most abstract and philosophical; it refers to physical substance in a general, scientific sense ('the study of dark matter', 'organic matter'). In everyday conversation, 'stuff' is by far the most common; 'substance' and 'material' are used when you need to sound more precise or formal; 'matter' is rare outside scientific or philosophical contexts.

Etymology

GreekFrenchEnglish

The word 'stuff' entered English from Old French 'estoffe', meaning supplies, provisions, or materials. The French word likely came from Greek 'styppein', meaning to pull or prepare flax fibres for spinning. Over time, the meaning shifted from 'materials or supplies' to 'any unspecified substance or collection of things'. The verb form developed from the idea of filling something with material — originally with cloth or stuffing for cushions and saddles — and later expanded to the many senses we use today.
