Mr. Doe is committed to learning and teaching language and culture.
Is there a term that embodies both language and culture? I want something concise, as I need to state it multiple times.
I considered "linguistics" as a possibility:
Mr. Doe is committed to learning and teaching linguistics.
... but that doesn't really embody the customs and cultural side of the issue. I'm looking for a word that encompasses that aspect, as well as language.
