Why is the ninth month called September?
Old English seolfor, Mercian sylfur "silver; money," from Proto-Germanic *silubra- (cf. Old Saxon silvbar, Old Frisian selover, Old Norse silfr, Middle Dutch silver, Dutch zilver, Old High German silabar, German silber "silver; money," Gothic silubr "silver"), from a common Germanic/Balto-Slavic term (cf. Old Church Slavonic s(u)rebo, Russian serebro, Polish srebro, Lithuanian sidabras "silver") of uncertain relationship and origin. According to Klein's sources, possibly from a language of Asia Minor, perhaps from Akkadian sarpu "silver," literally "refined silver," related to sarapu "to refine, smelt."
As an adjective from late Old English (cf. silvern). As a color name from late 15c. Of voices, words, etc., from 1520s in reference to the metal's pleasing resonance; silver-tongued is from 1590s. The silver age (1560s) was a phrase used by Greek and Roman poets. Chemical abbreviation Ag is from Latin argentum "silver," from the usual PIE word for the metal (see argent), which is missing in Germanic.
"to cover or plate with silver," mid-15c., from silver (n.). Meaning "to tinge with gray" (of hair) is from c.1600. Related: Silvered; silvering.

A soft, shiny, white metallic element that is found in many ores, especially together with copper, lead, and zinc. It conducts heat and electricity better than any other metal. Silver is used in photography and in making electrical circuits and conductors. Atomic number 47; atomic weight 107.868; melting point 960.8°C; boiling point 2,212°C; specific gravity 10.50; valence 1, 2. See also sterling silver. See Periodic Table. See Note at element.
Money: silver under the mattress
used for a great variety of purposes, as may be judged from the frequent references to it in Scripture. It first appears in commerce in Gen. 13:2; 23:15, 16. It was largely employed for making vessels for the sanctuary in the wilderness (Ex. 26:19; 27:17; Num. 7:13, 19; 10:2). There is no record of its having been found in Syria or Palestine. It was brought in large quantities by foreign merchants from abroad, from Spain and India and other countries probably.
