My native language is Cebuano. Although technically a dialect, it's the language I first learned to speak as a child. It's what we spoke at home. My second language is English since it's the primary medium of instruction in school. Plus, all the TV shows I watched growing up were in English. I remember memorizing the commercials and reciting along every time they came on. Then we had Chinese class from kindergarten up until high school. I never really learned to speak Chinese though, just some words and common sentences. I got by with memorizing the answers on the exams year after year. Still, you could say Chinese is my third language. In elementary we were introduced to Filipino a.k.a. Tagalog, our national language. Ironically, I found that to be the most difficult subject in school. Until now I speak broken Tagalog at best. But broken or not, it's still my fourth language.
And now I'm studying Japanese, my fifth language. This time I'm learning it because I want to, not because it's required by the school. So now can I say that I speak five languages?
But no, wait... I studied Spanish for one semester in college and got a flat 1.0 (perfect grade). Then I speak six languages?! Hahaha! #justhavingfun
