presume

To presume means to think something is true before you have full proof. Usually there is some reason for that belief, so it is more than a wild guess. You might think a friend likes chocolate because they always pick it for dessert, or a detective might believe a suspect had a motive based on early evidence. The word can also suggest acting too confidently, as if you already know the answer. In law, it is often used for something the court accepts as true unless someone proves otherwise.

To presume is to treat something as true or likely before you have full proof. It is more than a random guess; there is usually some reason behind it, even if that reason is incomplete. For example, saying "I presumed she was coming to the party since she said she was interested" shows that you had a basis for your belief, even if you were not fully sure.

However, the word can also have a negative sense, suggesting too much confidence. To presume upon someone's kindness means to take unfair advantage of their generosity. In the sentence "He presumed he would get the job just because he knew the manager," the idea is that his expectation was too bold and not well supported.

In legal contexts, it has a more exact meaning: something is accepted as true unless evidence is brought to challenge it. This appears in the basic principle that a person is presumed innocent until proven guilty.

The word comes from Latin roots meaning "to take beforehand." In other words, when you do this, you reach a conclusion before all the facts are known. It is a flexible word that can describe ordinary daily assumptions, social overconfidence, and important legal ideas. The main idea is simple: there is usually some basis for the belief, but not complete proof yet.
