First: there's a typo in the title (capital i).
Then: the source is - sorry to say - rubbish in many aspects:
- Esperanto is not considered "fictional", even though it is a constructed language. A fictional language would be one from a work of fiction, but this is a language "from the real world" constructed to be easy to learn and apply. There are even native speakers of Esperanto these days (!) - children of two Esperanto speaking parents who chose to raise their kids tha way (most of them are bi- or trilingual of course). That's not fictional in any respect. (Easy to guess still, because of Zamenhof)
- "Elvish" does not exist within the works of Tolkien, there are different languages (which should be accepted in this quiz by the way, most notably Sindarin and Quenya, as alternative answers).
- For a language to fall into the category of "can be learnt", it should be fleshed out well enough by canon or at least fanon sources to offer basic communication opportunities, not just random words and sentences. This only holds for Sindarin and Klingon of the above (and of course Esperanto). All the others lack grammar rules, a large enough vocabulary, so you're left to the few sentences actually mentioned in the works.
- this is not an unambiguous thing, but the status of Nadsat and Newspeak as a "language" is dubious (even though Newspeak is often referred to be one), since both are actually English with an in parts different vocabulary. |
