It's common and wrong. I had to do "ESL" courses at a Canadian secondary school, even though English is my third language, not second.

Ha, technically correct but also a little nitty. "First" and "second" are colloquial used here as "main" and "other." But again, you're not wrong.

[koakuma-chan]

Even if we were to admit that "first" meant "main" and "second" meant "other," it would still be wrong, because it is possible for your first language to no longer be your main language, which is the case for me.

[sodapopcan]

Right. Again, it's colloquial. These things happen in languages.

[koakuma-chan]

I know, just felt like being nitpicky :)

[sodapopcan]

All good :D

Is this thread just toying with the metrics?

[neutronicus]

"Subsequent Language"? "Successor Language"? "Secondary Language"?

Feel like there is an "S" word that works
