Introduction to Irregular Verbs: Be, Have, Do, and Say

Khan Academy

This video provides a clear and accessible introduction to irregular verbs in English grammar. The narrator distinguishes between regular verbs, which follow standard conjugation patterns (like adding "-ed" for past tense), and irregular verbs, which change form in unpredictable ways. Using specific examples like "talk" versus "run," the video illustrates the difference in a visual, easy-to-follow format. The core of the lesson focuses on four of the most common and important irregular verbs: "be," "have," "do," and "say." The narrator constructs a grid to map out these verbs across different tenses (present and past) and points of view (first person, third person singular, and plural). Special attention is given to pronunciation shifts, particularly with words like "says" and "does," which often confuse young learners. For educators, this resource is an excellent tool for demystifying English grammar. It breaks down abstract rules into a concrete visual table, making it ideal for visual learners and students struggling with conjugation. It is suitable for upper elementary grammar lessons, ESL/ELL instruction, and remediation for middle school students who need to solidify their understanding of foundational verb mechanics.
