To find the past tense of an irregular verb, you can consult a dictionary or online resources specifically designed for English language learners. One common example of an irregular verb is the word "go." The base form or infinitive is "go," and the past tense is "went." So, by looking up the verb "go" in a reliable source, you will find that "went" is the past tense form. This method can be applied to other irregular verbs as well, such as "be" (base form) and "was" (past tense), or "do" (base form) and "did" (past tense). Remember that irregular verbs do not follow the usual pattern of adding "ed" at the end to form the past tense like regular verbs do.
