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!
