What is a basic definition of consider?

Consider means to think carefully about something, to deem one thing as being another, or to believe something. Consider has several other senses as a verb.

When you are considering something, you are thinking very hard and very seriously about it, especially when you have to make a decision. The act of considering or something that is considered is called consideration.

  • Real-life examples: An investor considers how risky a business is before giving money to it. Hollywood casting agencies consider many different actors and actresses for roles before choosing people. You might consider whether studying for tests will improve your grades (spoiler alert: it will).
  • Used in a sentence: I didn’t consider my friend’s peanut allergy when deciding where we should eat lunch. 

Consider also means to regard one thing as being another. For example, modern scientists no longer consider Pluto to be a planet. Often, this sense of consider is based on a person’s opinion or beliefs rather than facts. However, it is possible that this sense of consider is based on science or truth, as with Pluto (sorry, Pluto fans!).
