If you could provide us with the context, it would be helpful. I have only heard SLK once and it was used to describe a type of Mercedes-Benz car.

Sounds Like Korean? If your teacher wrote it on your sentence maybe it is a code. You should ask your teacher!

Yuri: I have no idea what SLK is an abbreviation for. I looked on the Internet and found nothing. Could it be the initials for the teacher's name?
