What is the most "direct" term for a linguist in Russian? Лингвист is like an interpreter, but does that mean that a linguist is a филолог? --because linguistics is really not philology... but then... an interpreter is really not a linguist!

...and does the "professional" translation of историческое языкознание translate "historical linguistics" well?

P.S. Does бабушка really conjure up the same stereotypical image in Russian as it does in English (according to an irritated Russian friend)? If so, how on Earth does one talk about one's grandmum in Russian?!?
