Could it be "ethnolinguistics" (or simply "cultural linguistics")?
I hope the link will shed some light on your query.
could you help me choose the name of a science (a branch of linguistics studying culure through the language) which would sound most "natural" to the ear of a native speaker:
1) linguistic and culture studies
2) linguistic and cultural studies
3) lingvistic culturology
If I were a native speaker of English, I would never shut up. :-)
2 is the best of the four. 3 & 4 are out of the question. tzfujimino's suggestions are both better than 2.
