Etymology
Origin of laboratory
1595–1605; < Medieval Latin labōrātōrium workshop, equivalent to Latin labōrā ( re ) to labor + -tōrium -tory 2
Explanation
A laboratory is a place where experiments happen, usually scientific experiments involving chemicals and lab coats, but there are creative and athletic laboratories too, where people experiment with writing and footballs. When you think of a laboratory, you might see men and women wearing face masks pouring colorful liquids into test tubes, and you’d be correct. Any place that is a testing ground for new ideas is a laboratory, like a class full of people thinking up new ways to make paper airplanes. The Latin verb laborare means “to labor,” so remember that a laboratory is a place of hard work: you can’t spell laboratory without labor in it.
