Here in Malaysia there are three main ethnicities, Malay, Chinese, Tamil, and most people speak more than one language.
There are four main language groupings:
- Malay - national language and language of the ethnic majority.
- Chinese - Hokkien, Hakka, Cantonese, Teochew, Mandarin, and other varieties are all spoken among parts of the ethnic Chinese Malaysians.
- Tamil - by far the most commonly spoken language among the ethnic "Indian" Malaysians, who are mostly ethnic Tamils.
Here's the generalization / expectation:
- Malays speak Malay and often English to some degree.
- Chinese speak one or more Chinese variety and often either or both Malay and English.
- Tamils speak Tamil and usually English and often Malay.
Now I had been wondering for the past couple of weeks how common it is for Indians here to speak Chinese or for Chinese here to speak Tamil. It doesn't seem to be usual.
But then two days ago I arrived in Penang and I was talking to a local Tamil who told me he spoke Tamil, Malay, English, and (Mandarin) Chinese, in that order. Not long after this I observed an ethnic Chinese talking to the same guy in fast fluent Tamil.
Are there some statistics or studies on how common this is in Malaysia?
(For the sake of this question I'm interested just in this pair. I am aware the linguistic and ethnic situation here are both much more complicated than I have this simplified intro in my question.)
