Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'субстанция' in everyday contexts; it's a philosophical term. Use 'вещество' for physical matter or 'суть' for the core meaning.
- Do not confuse with 'substantial' (значительный) in all cases; the link is conceptual, not direct translation.
Common Mistakes
- Using 'substance' as a countable noun for abstract 'importance' (*He provided three substances to his claim).
- Confusing 'substance' with 'object' (a substance has no defined shape, an object does).

Frequently Asked Questions
No. While its primary meaning refers to physical matter, it is commonly used metaphorically to mean the essential, meaningful, or most important part of something non-physical (e.g., an argument, a book, a person's character).
They are often interchangeable for physical matter. However, 'substance' often emphasises chemical composition or intrinsic properties, while 'material' often relates to something used to make or build things (e.g., building materials). 'Substance' also has the abstract meaning of 'core importance,' which 'material' lacks.
