The Buenos Aires Linguistics and Philosophy of Language Group (BA-LingPhil) is a research team focused on the problem of language meaning from a linguistic and philosophical perspective. Since its origin, the BA-LingPhil group has been concerned with different aspects of the proper (meta-)semantic representation of meaningful linguistic expressions. In this respect, we have explored different issues in the philosophical and linguistic tradition involving, mainly, the analyses of proper names, indefinites, modals, expressives and evaluatives. The importance of such topics for current debates around the problem of compositionality, the semantics-pragmatics interface and the representation of truth-conditional and non-truth-conditional content is without a doubt at the heart of the linguistics and philosophy of language connection.
