You can study both anthropology and a language as part of a Bachelor of Arts (i.e. a single degree). Within that single degree, you can double major (so have two primary areas of study). If you're interested in a double degree, what else would you be thinking of studying? So like, Science, Laws, Commerce?
And sure! You can see my review of the Linguistics major right here.
I'm not entirely sure, but I think under a single Bachelor of Arts, beverlycheeeee would be able to do an anthropology major, linguistics major, and still have room to do 2 language minors (or anthro major, lang major, ling minor, lang minor)? 8 units for anthropology, 8 units for linguistics or language, leaving another 8 in year 1 and 2
according to the map, unless I'm misinterpreting it or forgetting a detail/rule. If my interpretation is correct, studying anthropology, linguistics, Japanese, and Korean in one degree is possible!
As a side comment, I'm doing first year linguistics (hopefully to carry through as a major) at the moment and can vouch that it is enjoyable so far. Also doing introductory Korean (probably will minor in it) and finding it fun too. Staff in both areas are superb. Since you've done KSL though, you have to take a test and it will likely make you follow the intermediate Korean stream if you wish to do Korean studies (details on this is located on the Korean studies handbook entry). In that case you'd be taking 'culture' units in first year for Korean instead of actual language units.
