assumption

In most everyday conversations, "assumption" refers to believing something is true without having evidence. When used this way, it is often followed by the word "that" to explain what is being believed. The meaning related to taking on a responsibility (like a job or power) is more formal and is commonly found in business, legal, or military documents. Be careful not to confuse this with "presumption," which is similar but often implies that there is some reason or probability for the belief.
