The word "squint" refers to the action of partially closing your eyes to see something more clearly, often in response to bright light or to focus on something in the distance. When someone squints, they might be trying to reduce glare or strain while looking at an object that is hard to see clearly.
The word "squint" originates from the mid-17th century, derived from the Scottish word "squinte," which means "to squint or look sideways." It is thought to be related to the Old Norse word "skyntr," meaning "to squint" as well.
