I stopped counting after 13 languages, but I still think the number is less than 20. It really doesn't make sense to count all the languages if I only know few words or sentences.

On daily basis, I only use about 5 languages, so in those I'm better than with the remaining languages. I can recognize text written in all of the languages, but I still do need dictionary to translate many of the words.

In some of the languages, like Tagalog, I know some words that native speakers don't use anymore, as the words are considered archaic, so only older people know the correct meaning.
