What is the Difference Between Assume and Presume?

The words "assume" and "presume" both mean "to take something as true" or "to take something for granted," but they differ in the level of certainty and the basis for that certainty. Here are the key differences between the two terms:

• Assume: To assume is to suppose or believe something without any proof. It is often used when making a guess based on little or no evidence. In this context, the assumption is considered to be less certain and more tentative.
• Presume: To presume is to take something as true or entitled to be believed, based on reasonable evidence. It is typically used when making an informed guess grounded in probability. In this sense, a presumption is considered to be more certain and confident.

In summary, while both terms involve taking something as true, "assume" is used when there is little or no evidence to support the belief, whereas "presume" is used when there is reasonable evidence to support the belief.

Examples of using "assume" and "presume" correctly:

• I assume he will be late to the meeting.
• I presume she will be at the party, as I saw her RSVP on the invitation.

Remember that "assume" is often used when there is no concrete evidence, while "presume" is used when there is some evidence supporting the conclusion.
