Laboratory
A place for doing tests and research procedures and preparing chemicals, etc. Although “laboratory” looks very like the Latin “laboratorium” (a place to labor, a work place), the word “laboratory” came from the Latin “elaborare” (to work out, as a problem, and with great pains), as evidenced by the Old English spelling “elaboratory” designating “a place where learned effort was applied to the solution of scientific problems.”
