How many languages do you know in terms of understanding it well and speaking it at least to a certain extent understandable to the other person.
Its more about knowing how many languages people are exposed to.

Personally, I know:
Kachi - Mother tongue; fluent and good vocabulary
Gujrati - fluent with good vocabulary
Hindi/Urdu - They are pretty much the same with slightly different ways of speaking and vocabulary; not fluent but understand very well with good vocabulary
Swahili - National Language; quite fluent since i dont talk too much and have an okay vocabulary but still need lots of practice
English - fluent and better vocabulary than any other language

I could add Arabic but i understand little and hardly talk it.

So how many and how much do u know?

 

I am from the Netherlands so its quite obvious I can speak, write, read and understand what people are saying.
English: I can speak it wright it read it understand it.
French: can generally read it speak it and understand what people are saying though writing it, not so much.
German: I can do the same as with French but a little worse on all fronts.

 

For me,
English - 1st language in school and at home, decently fluent
Mandarin - (Supposed-to-be) 2nd language. I hardly speak it. Always off-key.
Japanese - 3rd language. Reading okay, speaking and writing horrible.
Malay - ONLY COMMANDS. I'm one of the leaders in a uniformed group. Other than commands, I don't know anything else.

 

english - native
chinese - native
japanese - some phrases and words, still learning
spanish - 5 years of it in school

 

English- Almost native, have 2 proficiency degrees
Greek- native
French- I'm pretty fluent
Italian- I'm still learning
Japanese- Meh... I have to work harder with it

 

spanish - native language
english - can understand it well, but not so fluent at speaking/writing
italian - same as english but I find it impossible to write/read

 

Gujarati- Mother Language. Understand it well, but can barely speak it and can't write
English- Can read/write/speak
German-school, very basic.

 

Er..
English
Romanian
Russian
Ukrainian
Hebrew (a little)
1337
Slang

 

In our community, scholars who go to Iran for religious studies learn 2 languages over the ones i know so its farsi and arabic
so they basically know 7 languages (or 8 if u count hindi and urdu separately)

from amongst us, it seems animemaster is the biggest/most proficient polyglot

Let me also add that the best two programs i have seen for learning languages is
Rosetta Stone - Pretty famous; visual images with text presented in the language; audio speech; slow but definitely good memory obtained; teaches to read, speak a little, and write (or type); words given arent that normally used; some have upto 5 levels but usually 3 on famous languages such as french; formal speech, reading and writing
Pimsleur - Best way to understand and speak a language; ONLY AUDIO; teaches to make you fluent in speaking; usually 30 lessons on every language but famous languages have 90 lessons which would definitely make u fluent; half an hour lessons everyday; informal speaking and listening

I suggest starting with pimsleur then shifting to rosetta to learn more words and get more used to formal ways of speaking/reading

@animemaster NahuelDS probably doesnt know italian as good as a native speaker bcz he dont speak much like i dont know swahili that is my national language
