What is origin of the word "Laboratory". Its surely not Labor, is it?
1. a building, part of a building, or other place equipped to conduct scientific experiments, tests, investigations, etc., or to manufacture chemicals, medicines, or the like.
2. any place, situation, set of conditions, or the like, conducive to experimentation, investigation, observation, etc.; anything suggestive of a scientific laboratory.
[Medieval Latin labōrātōrium, from Latin labōrāre, to labor, from labor, labor.]
[Origin: 15951605; < ML labōrātōrium workshop, equiv. to L labōrā(re) to labor + -tōrium -tory2]
