How many fictional languages can you learn?

Vulcan? Romulan?

I’ve made up about 2 bogus languages in the course of dealing with telemarketers and various other people.

Here’s a convo I had with a Tm awhile ago:

Tm: Hello, who am I speaking to?

Me: Cheena malamaboombo.

Tm: Could you please repeat that, sir?

Me: Nyarka tamblosavich.

Tm: This is BJ Construction & Renovation. What time would you like us to come by and start criticizing your house?

Me: Cthulhu inna moomoo, mawma clonko bama!

Tm: I’m sorry sir, but I don’t understand what language you’re speaking.

Me: Most earthlings have trouble with multi-lingual Kepleranian dialects. <click>

Mastering my 2 nonecahedrons of neologisms is good enough for me.

Trying to master French and Hebrew are enough for me. if I encounter an Ent, I’ll use Google translate.

I also prefer to learn the ones that I actually utilize. French, Italian, and Spanish work for me as I visit places that have them as native tongue.
Use it or lose it.

Okay, but how many fictional languages are developed like Klingon is? I believe Lord of the Rings fans learned to speak Elvish.

Watch this article about made up languages
More than you know.

A small group of girls (only) had, and still have, a language that no one else knows. We started in high school and as recently as nine years ago four of us got together and laughed so hard recognizing it was still as easy today as it was back then. I did teach my sister but she never could speak it, only understand it.

Why would I learn a language that no one else speaks?

I will watch that video in a bit.

I am looking for a list. Not input on who wants to learn what language.

That video is interesting thank you. To clarify for others: I mean how many fictional languages from franchises are fully developed and have fluent speakers. Sorry for the misunderstanding.

@elbanditoroso I guess you’ve never been a high-school girl.
