Excuse me, do you speak bahasa?
Humm.. I often hear non-indonesians refer to indonesian language as bahasa. “do you speak bahasa?” foreigners in Indonesia ask each other, in Russia and some europe country, I found out that some indonesian refer their own language as bahasa as well. And very sadly, some indonesian also do the same thing! :( Come on, you are the expert there, you should know so well that’s it’s wrong ;)
Oke, now I tell you this, In english bahasa is translated as “language”(refers to Indonesian-English dictionary by John M Echols 3rd edition p.41)
for example, I speak bahasa inggris(English), bahasa indonesia(Indonesian), and bahasa rusia(Russian). All languages are bahasa, everybody in the world speak bahasa, of course their own bahasa.
The word bahasa doesn’t mean anything but “language“. If you want to use Indonesian word for “Indonesian”(language) then use the complete term “Bahasa Indonesia”
“Do you speak Indonesian?”
is much much better than
“Do you speak bahasa“
