Simplified etymology
Placebo is Latin for “I shall be acceptable or pleasing.” By the late 18th century, doctors used the term for a treatment given chiefly to satisfy a patient; it later came to denote an inactive substance used as a comparison in medical research.
Etymology
Inherited from Middle English placebo, borrowed from Latin placēbō (“I will please”), the first-person singular future active indicative of placeō (“to please”).
