What's the Difference Between 'Assume' and 'Presume'?

In this blog post we look at when to use assume and when to use presume.

'Assume' or 'Presume'?

"Presume" and "assume" are two different words with similar meanings. Both words can be used to mean "to suppose or believe something to be true without having proof."

However, there are some slight differences in the connotations and usage of these words.

"Presume" tends to be used in formal or legal contexts, and it often carries the sense of making an educated guess based on available information.

For example, you might say "The court presumes the defendant to be innocent until proven guilty."

"Assume," on the other hand, is more commonly used in everyday speech and can carry the sense of taking something for granted or making an assumption without considering all the facts.

For example, you might say "I assumed that the store would be open on Sunday, but it was closed."
