placebo: placebo: [13] Placebo started life as the first person future singular of the Latin verb placēre ‘please’ (source of English please), and hence meant originally ‘I will please’. It was the first word of the antiphon to the first psalm in the Roman Catholic service for the dead, Placēbo Dominō in rēgiōne vivōrum ‘I will please the Lord in the land of the living’. The word’s medical use emerged at the end of the 18th, and arose from the notion of a medicine ‘pleasing’ the patient rather than having any direct physiological effect.
=> please
placebo (n.): early 13c., name given to the rite of Vespers of the Office of the Dead, so called from the opening of the first antiphon, "I will please the Lord in the land of the living" (Psalm cxiv:9), from Latin placebo "I shall please," future indicative of placere "to please" (see please). Medical sense is first recorded 1785, "a medicine given more to please than to benefit the patient." Placebo effect attested from 1900.
