The following passage on learning languages in the wiki has been altered to be more clear:
Learning Languages
Learning and leveling languages is different than learning and leveling skills. Though they both follow the same process of the point buy system, languages are easier or harder to learn depending on which language it is.
When you encounter a new language within an RP, be sure to let your reviewer know. It is up to them to reward you with the knowledge, Language: _____. Once your character has been introduced to this language, they may begin studying this as they would any other skill. However, just because your character has been introduced to the language doesn't mean they can speak it just yet.
With the following added to the end of it:
These language-specific knowledges can either be learned as non-skill knowledge, or under the skill Linguistics, depending on the wishes of the player.
For instance say your PC learns that Grovokian sounds like a wet, whining dog, if you want it to be non-skill knowledge that counts toward learning the language, you'll list it as follows: Language: Grovokian: Sounds like a wet whining dog.
If you wish to learn this language as part of the Linguistics skill, you can list request it from the reviewer as follows: Linguistics: Language: Grovokian sounds like a wet, whining dog.
In both cases, these knowledges count toward the amount of knowledges needed to learn a new language, or improve one's use of a language they already have.
I hope this helps clarify any questions you have regarding the learning of new languages!
EDIT: For those of you who have already claimed the language knowledge as non-skill, you will be allowed to claim it under linguistics skill from now on. Language knowledges counting toward Linguistics skill will count toward the maximum of skill knowledge rewarded for threads and such, so be mindful of that if you choose to claim them as knowledge.
