Noun that means ‘person able to read, write, speak, and comprehend a language’?

Question

Would you please introduce me a Noun that means ‘person able to read, write, speak, and comprehend a language’?

I know- a noun ‘literate’ means ‘person able to do 2 skills, reading and writing’ -, but need to know the Noun that means ‘person able to do 4 skills, reading writing speaking and comprehending’.

I need to use the Noun in a question that will be titled “Verb that means ‘order’” and posted by me at ‘General- Education & Reference’, ‘Higher Education’, and ‘Words & Word Play’ section of this Yahoo Answer.

I searched the Noun at following 8 thesaurus websites for two hours until 15 minutes ago, but could not find the Noun during the search:
answers.com/library/thesaurus, encarta.msn.com/thesaurus, infoplease.com/thesaurus, m-w.com/thesaurus, online-thesaurus.net/thesaurus, synonym.com/synonym, thesaurus.reference.com, wordnet.princeton.edu.

I typed:

‘letterer’-‘lingual’-‘literate’. -‘literacy’- -‘reader’--‘inditer’-. ‘penner’-‘writer’--‘articulater’-. ‘deliverer’-‘emitter’-‘expresser’-. ‘mouther’-‘phraser’-‘sayer’. -‘sounder’-‘speaker’-‘stater’-. ‘talker’-‘teller’-‘utterer’. - ‘verbalizer’-‘vocalizer’-‘voicer’. -‘worder’-- ‘appreciater’- ‘apprehender’. -‘assimilater’-‘catcher’-‘comprehender’. -‘compasser’-‘conceiver’-‘digger’. -‘grasper’-‘penetrater’-‘seer’. - ‘seizer’-‘senser’-‘taker’. -‘twiger’-‘understander’-.
on search bar of above websites,

then clicked a rectangle button at dexter adjacence of the bar a second after the type --search result page was displayed for the typed words at the website a second after the type -- and searched the Noun at the page.

Thank you for your time and help!

Answer 1

Would fluent work?

If someone tells me that they are fluent in French then I assume that they can read, write, speak and understand the language.

Answer 2

A individual equipped to recognize, learn, write and talk languages might be a individual who's literate in the ones places. A individual can also be "literate" in a single discipline, 2 places, or extra....you simply have got to specify what topics they're "literate in. I am absolutely careworn by way of the assertion you wish a noun that's indexed as a verb.....and "literate" can be utilized as a noun....this individual is a "literate"....or as an adjective...."it is a literate individual."....and also you might say what that individual is "literate" in.....which might comprise any quantity of matters. If you wish a noun that suggests "order" it might be "group",association, submitting approach, and so on. relying on what you imply by way of "order".

Answer 3

Being fluent in a language means all of these things, but there is not a noun form in common usage. 'Fluent' is an adjective.

'Linguist' is a noun, but I believe that implies that the person is proficient in multiple languages.

Still, 'linguist' might work.
