However, some linguists consider the borrowing of words or morphemes from another language to be different from other types of code-switching

Ok, so some think it’s the same type, some think it’s another type, but all of them agree it’s code-switching…

Yes, sociologists care about how code switching languages is used in social situations. The phenomenon itself is just switching languages rapidly on-the-fly.

In linguistics, code-switching … occurs when a speaker alternates between two or more languages … in the context of a single conversation …
