Linguistics is the study of language as a phenomenon, NOT of individual languages. In first year, you will study the diverse patterns of sound and word structure across the languages of the world, try to find universal patterns in grammatical structure, and explore how developments in these areas can be applied in the real world. In the following two years of your degree you can tailor it to your specific interests.
The Linguistics tripos at Cambridge bridges the gap between Humanities and Sciences. Not only does this make the course diverse in terms of lecture content, but it also allows you to develop a broad set of skills due to the different ways you have to approach assignments.
