Actually, neither do linguists, in my experience.  It sounds really
odd to me to refer to Latin as an extinct language; the
traditional phrase "dead language" sounds much better.

I don't see how it could.  It is more analogous to what's called
"dialect borrowing", i.e. exchange between dialects of one language
or between closely- related languages.  The difference is that you
can get inter-language effects between *any* two (or more) languages
that are in contact, regardless of how similar or dissimilar they
are, and that these can be very fundamental effects that radically
alter the shape and organization of a language.
