from Latin Europa "Europe," from Greek Europe, which is of uncertain origin; as a geographic name first recorded in the Homeric hymn to Apollo (522 B.C.E. or earlier):
"Telphusa, here I am minded to make a glorious temple, an oracle for men, and hither they will always bring perfect hecatombs, both those who live in rich Peloponnesus and those of Europe and all the wave-washed isles, coming to seek oracles."
Often explained as "broad face," from eurys "wide" (see eury-) + ops "face," literally "eye" (from PIE root *okw- "to see"). But also traditionally linked with Europa, Phoenician princess in Greek mythology. Klein (citing Heinrich Lewy) suggests a possible Semitic origin in Akkad. erebu "to go down, set" (in reference to the sun) which would parallel occident. Another suggestion along those lines is Phoenician 'ereb "evening," hence "west."
word-forming element in chemistry, used to coin element names, from Latin adjectival suffix -ium (neuter of -ius), which formed metal names in Latin (ferrum "iron," aurum "gold," etc.). In late 18c chemists began to pay attention to the naming of their substances with words that indicate their chemical properties. Berzelius in 1811 proposed forming all element names in Modern Latin. As the names of some recently discovered metallic elements already were in Latin form (uranium, chromium, borium, etc.), the pattern of naming metallic elements in -ium or -um was maintained (in cadmium, lithium, plutonium, etc.; helium is an anomaly).
