Here's why:
* Definitions of "irregular": The term "irregular verb" is not completely clear-cut. Some verbs are considered irregular because their past tense and past participle forms don't follow standard patterns (like adding "-ed"). Others have unique spelling changes.
* Variations and subcategories: Some lists might include verbs that have multiple forms depending on context (like "to lie" vs. "to lay"). Others might include verbs that are only irregular in specific tenses or situations.
* Regional dialects: Even the way verbs are categorized as "irregular" can vary across different English dialects.
Instead of a fixed number, it's more helpful to think about the concept of irregular verbs:
* They don't follow the standard "add -ed" rule for past tense and past participle forms.
* They often have unique or unpredictable spellings.
* They require memorization.
To learn about irregular verbs, focus on understanding how they function and practice using them correctly. You can find lists of common irregular verbs in textbooks, online resources, and verb tables.
