Edited in collaboration with FoLLI, the Association of Logic, Language and Information, this book constitutes the refereed proceedings of the 24th International Conference on Formal Grammar, FG 2019, held in Riga, Latvia, in August 2019, in conjunction with the 31st European Summer School in Logic, Language and Information, ESSLI 2019.

The 7 full papers presented were carefully reviewed and selected from 11 submissions. They present new and original research on formal grammar, mathematical linguistics, and the application of formal and mathematical methods to the study of natural language and focus on topics such as formal and computational phonology, morphology, syntax, semantics, and pragmatics; model-theoretic and proof-theoretic methods in linguistics; logical aspects of linguistic structure; constraint-based and resource-sensitive approaches to grammar; learnability of formal grammar; integration of stochastic and symbolic models of grammar; foundational, methodological, and architectural issues in grammar and linguistics; and mathematical foundations of statistical approaches to linguistic analysis.
