SOL does indeed mean "Sun", but was actually an acronym for "Simple Object Language". It in turn was the successor to DEL (defined as a "dialog specification language", but that would be DSL in English or LED in Portuguese so I haven't figured that out). Anyway, having an acronym that is also a relevant word or name is a popular thing to do. The Wolfram Language is named after the author. The closest to that I can think of is Algol-W by Niklaus Wirth and Tony Hoare (that is if the W is for Wirth at all, which I couldn't verify). Are there any other cases?
