The book investigates the intricate relationship between time and modality in natural language. It delves into how temporal concepts influence modal expressions, exploring theories and linguistic data to understand the semantic and syntactic interactions. The work examines various linguistic frameworks and their capacity to model these complex phenomena, drawing on examples from different languages to illustrate its points.

This work is recognized as a significant contribution to the formal semantics of natural language, particularly concerning the interplay of time and modality. Scholars in linguistics and philosophy of language have noted its rigorous analysis and comprehensive scope. The book is considered a valuable resource for researchers seeking to understand the complex ways temporal and modal meanings are expressed and interpreted. Its detailed examination of theoretical models and linguistic data makes it a foundational text in the field.
