"complete set of characters of a particular face and size of printing type," 1680s (also fount); earlier "a casting" (1570s); from French fonte "a casting," noun use of fem. past participle of fondre "to melt," from Latin fundere (past participle fusus) "to melt, cast, pour out" (from nasalized form of PIE root *gheu- "to pour"). So called because all the letters in a given set were cast at the same time.

Earlier in English as achate (early 13c.), directly from Latin. The Elizabethan sense of "a diminutive person" is from the small figures cut in agates for seals, etc., and the notion of smallness is preserved in typographer's agate (1838), the U.S. name of the 5.5-point font called in Great Britain ruby. Meaning "toy marble made of glass resembling agate" is from 1843 (colloquially called an aggie). Related: Agatine.
not in the Roman alphabet, but the Modern English sound it represents is close to the devocalized consonant expressed by Roman -U- or -V-. In Old English, this originally was written -uu-, but by 8c. began to be expressed by the runic character wyn (Kentish wen), which looked like this: ƿ (the character is a late addition to the online font set and doesn't display properly on many computers, so it's something like a combination of lower-case -p- and a reversed -y-).
In 11c., Norman scribes introduced -w-, a ligatured doubling of Roman -u- which had been used on the continent for the Germanic "w" sound, and wyn disappeared c. 1300. -W- is not properly a letter in the modern French alphabet, and it is used there only in borrowed foreign words, such as wagon, weekend, Western, whisky, wombat.
