Geneva was originally a redesigned version of the famous Linotype typeface Helvetica; the TrueType version of the font is somewhat different. Helvetica comes from the Latin name for Switzerland, in which sans-serifs of this type are very popular; Geneva is Switzerland's second-largest city.
The bitmap version varied by appearance in different sizes; in smaller sizes, the lowercase i, j and l had serifs on the top, the lowercase y was parallel, and the 3 had a flat top. Larger sizes of the font depicted said characters as how they appear in the TrueType version.
Unusually for neo-grotesque faces, the current version of Geneva includes a basic set of ligatures and the archaic long s and R rotunda as optional alternates.
A slightly modified version of Geneva known as Simple can be found in the Apple Newton operating system.
