Why was "tantrum" trending last week?
mid-15c., amalettys, from Latin amuletum (Pliny) "thing worn as a charm against spells, disease, etc.," of uncertain origin, perhaps related to amoliri "to avert, to carry away, remove." Not recorded again in English until c.1600; the 15c. use may be via French.
an object, either natural or man-made, believed to be endowed with special powers to protect or bring good fortune. Amulets are carried on the person or kept in the place that is the desired sphere of influence-e.g., on a roof or in a field. The terms amulet and talisman are often used interchangeably, but a talisman is sometimes defined as an engraved amulet.
