I want to know the answer to the following question:
What does it want to do with the language, the speakers, and reality?
All the background I'm provided with is that "It is a subdiscipline of Catalan philology and other affine studies and has as an objective to analyse the relation between the Catalan language, the speakers and the close reality (including the one of other languages in contact).". Is that enough to answer the question?
Answer: yes
