This book explains how to understand Thai tenses naturally from the context. Whether the sentence refers to the present or past time depends on the five different types of verbs and the time indicator "Laeo". In addition to the natural time aspect, the reader will also learn how to use time words, tense markers and express anticipated future time.

The Thai time aspect is entirely different from the English tense system, which can be rather complicated. In Thai, instead of tenses, we focus on:
- pàt-tsùbanna-kaan present time, now or nowadays
- adìitta-kaan past time or completed actions
- anaakhótta-kaan future time or future planning

This book is for anyone who wants to learn and improve their Thai language skills. If you are an intuitive person, concentrate more on spoken and written sentences. If you are more grammar-oriented, focus on the explanations and grammatical rules. The book provides numerous example sentences, along with audio spoken by native speakers, to help you get into the flow of the language. When you master the Thai tenses with "Laeo", your language skills will improve significantly.

In this three-book series, we have two exciting titles coming soon.

The second book, Mastering Thai Language and Grammar (Book III), offers a comprehensive overview and introduction to a range of fascinating idiomatic and colloquial expressions.
