Understanding English grammar can be challenging, especially when it comes to specific parts of speech like modal verbs. Modal verbs play an essential role in shaping the meaning of sentences, providing subtle nuances that make communication more precise. This blog post will guide you through what a modal verb is, what modal words are, and how they are used in English grammar. We’ll also include examples to help illustrate these concepts clearly.
