Nice blog! It surprises me that you didn't chose Ithkuil or Ilash as well.My own top ten would be10)derjf3trunn: My favtoriue What-If conlang (What if a language which descended from Latin had evolved in a similar way to Icelandic?)9)Esperanto: Mainly for its noble purpose.8)Toki-pona: Both because its polynesian-like sound and for its simplicity.7)Lojban: Quite the opposite, I like it for its grammar an objectivity.6)Interlingua: Because IALA really made a good work towards creating a language who is both quite regular (although not as much as I'd like it to be) and easy to understand for millions of people.5)Na'vi: Because I love its grammar (I can't think of a language with such unambiguous word-order freedom, not to mention the laudative and the pejorative infixes)4)Lingua Franca Nova: Because LFN has all the advantages of Interlingua but is much more regular, much simpler and much more beautiful.3)Ithkuil: Because its superb grammatical features.2)Quenya (either Tolkien's or neo-Quenya): Because the beauty of this conlanging masterpiece can only be compared to 1)Sindarin: which, although its sound isn't better than Quenya's, has a number of interesting grammatical features such as its plural formation or the Celtic-like consonant mutations.However, I feel I should have also included Tapissary (even though it isn't a spoken language) and Kēlen, Sylvia Sotomayor's verbless language.I'll keep on reading you!
