Classification

Conlangs are sometimes divided into three groups:

• artlangs, those devised for artistic purposes -- either per se, or for use in fiction.
  • Klingon
  • Tolkien languages, which have given tengwar orthography to Lojban
  • Láadan
  • Glaugnea
  • Solresol
  • pc:

    Really for artistic purposes? Its purpose seems to have been IAL, the "esthetic" side - the musical version -- was partly practical (tone carries farther than words and is easier to pick out in a noisy environment) and partly either a bad joke or a misunderstanding of the claim that music is the universal language (which is clearly false even when rightly understood).

• loglangs, more recently called engelangs (Engineered languages), those devised according to some sort of objective principles; Lojban Description is one of these.
• auxlangs, those devised principally as IALs
  • a posteriori
    • Blissymbols

• • • Esperanto
    • Basic English
    • Interglossa
    • Latino sine Flexione
    • Interlingua
    • Lengua Global
    • Lingwa de Planeta
    • Romanova
    • Mondlango
  • Ygyde
  • Unish
  • Inoffensish
  • a priori
    • Sona (except for some borrowed radicals)
    • ru'a lo me la'o ly. a priori .ly bangu ka'e se pilno fi le nu satci cusku lo smuni be lo gismu

These categories are of course overlapping.
