Metallotherapy comes from the Greek roots *metállos* “metal” and *therapeía* “treatment”. First recorded in German scientific literature in the mid‑19th century, the term entered English by the early 20th century to describe medical uses of metals, and later broadened to alternative‑medicine practices.
Salary comes from the Latin word *salarium*, originally meaning “salt money” paid to Roman soldiers. The term traveled through Old French *salaire* before entering Middle English. Today it simply denotes regular pay for work, but its roots lie in the ancient value of salt.
Pentothal derives from the trade name of the barbiturate sodium thiopental, first marketed in the 1930s. The name fuses the Greek‑derived chemical prefix “thio‑” (sulfur) with “pent‑”, referring to its five‑carbon chain, and the suffix “‑thal” from “barbital”, the parent barbiturate family. It entered English medical vocabulary soon after its synthesis.
The English verb *collocate* comes from Latin *collocare* ‘to place together’, a compound of *com‑* ‘with’ and *locare* ‘to place’. It entered Middle English in the late 16th century, first meaning ‘to put side by side’, and later taking on a specialized linguistic sense in the 20th century.
Anamorphosis comes from Greek *ana‑* “up, back, again” and *morphē* “shape, form”. The term was first coined in the early 19th century to label a visual art technique where a distorted image becomes recognizable only from a particular angle or with a reflective device. It entered English via French *anamorphose* around the 1820s.
The English adjective “abrupt” comes from Latin abruptus, meaning “broken off” or “steep.” It combines the prefix ab‑ “away” with ruptus, the past participle of rumpere “to break.” The word entered Middle English in the 14th century, first describing cliffs and sudden actions.
Mistreat comes from the Latin prefix mis‑ meaning “wrongly” combined with the Old French verb traiter, itself from Latin tractare “to handle”. The compound entered English in the late 16th century, originally meaning “to handle or deal with badly”. Today it denotes cruelty or neglect toward a person or thing.
“Assassin” comes from the Arabic hashshashin — the plural of hashshash (hashish user) — a name applied to members of the Nizari Ismaili sect of medieval Islam, whose fighters were feared for targeted political killings. The name was recorded by Crusaders and travelers including Marco Polo, who associated the sect with the drug. The Arabic plural became the medieval Latin assassinus and entered European languages through Italian and French.
“Companion” comes from Late Latin companio — literally “one who shares bread” — from com- (together, with) + panis (bread). In a world where sharing a meal was a bond of loyalty and trust, the word for a trusted fellow was built from the act of breaking bread together. The same “panis” root gives us company, accompany, pantry, and the French surname “Dupain” (of the bread).
“Hazard” comes from the Arabic az-zahr (the dice — literally “the flower,” from the markings on dice). The word entered Spanish as azar (chance, accident) and then Old French as hasard — a dice game that Crusaders learned in the Middle East and brought back to Europe. The dice game became a general term for chance, and chance became a term for risk.
