The point? To be contrarian. I've read a few of these how-to-write-a-fake-language guides, often they are strong proponents of language inappropriate for fan consumption, or in appropriate for script writer consumption (few/no script writers successfully wrote anything in Klingon)-- in other words, they are pro-Elivish. They are strongly negative about relexes, since that is what the naive fake language maker makes by default. The elitism of it just rubs me the wrong way.
I agree, if an author just needs a few flavor words, then no fake language is needed, relex or Elvish-style.
So I thought, when is a relex appropriate? The fans of Boba Fett liked the relex, they're a bunch of kids. The other time a relex is appropriate is when the *only* interesting idea is the phonology. Interestingly, the phonological description is where a lot of these elvish-is-good/relexes-are-bad hobbyists stop. Dritok, the squirrel language with no voiced consonants & lots of rare sounds is, imho, a language whose sole trick is the phonology-- As a fan, I'd rather interact with that language as a relex-- I could hypothetically make a cook foreign song in a relex that sounds pleasant without dedicating half a decade to learning exotic syntax.
And if a relex is appropriate, how to make a better one, preferably with the least effort possible. Furthermore, with a relex, machine translation is potentially trivial. One place conlangs are showing up is games, like magic the gathering. The MTG fake language was created by a pro-Elvish hobbyist without dictionary or grammar. People wasted lots of time trying to decipher the language and FAILED like the Japanese trying to decipher Navaho in WW2. If it was a relex, deciphering would be possible, but still an order of magnitude harder than a ceasar cipher. Put a crazy hard conlang in a game and leave it for fans to decipher-- it will just waste people's time and never be deciphered. (Unless that is the game, which I imagine that
re: rejection of relexes
Most conlangs are rejected out of hand by fans and the makers of these conlangs go one step further and reject fans and the possibility of fans, by doing something to make it really unlearnable. The most learnable language is one that is close to one's native language-- aside from condialects, no way to get closer to a mother tongue than a relex.
