The verb envision means to imagine or picture. Kids often envision themselves doing exciting things when they grow up, like being movie stars, professional athletes, or astronauts.
The word envision comes from the Latin en-, which means "cause to be," and visionem, meaning "a thing seen." Career paths aren't the only things that can be envisioned. If you envision a cleaner world, you may volunteer to pick up trash on the beach. If you envision a more peaceful world, you might make your brother and sister play in separate rooms to stop them from screaming at each other.
