I'm sorry, but "eubstance" is not a recognized or standard English word. It may be a misspelling or a term used in a very specific context that is not widely known. Perhaps you meant 'substance,' which refers to a particular kind of matter with uniform properties. π€ 'Substance' can describe something's physical makeup, like the substance of a cloud being water vapor. It can also refer to the essential nature or the significant part of something, like the substance of an argument. Make sure to double-check your spelling or provide more context if you're looking for information on a specific term.
