English is widely spoken around the world and is considered an international language. British and American English are the two most commonly spoken varieties of English, each with its own distinct characteristics. These differences can be observed in pronunciation, vocabulary, spelling, grammar, punctuation, style, and expression (Algeo, 2006: 1).
English language relies heavily on the verb, as it is essential to include at least one subject and verb in a sentence. But irregular verbs in American and British English can cause confusion due to their unpredictable nature. An interesting finding suggests that irregular verbs can be grouped based on shared sound changes, which can aid in memory retrieval. This book aims to redefine the categorization of English verbs by analyzing their inflectional patterns using morphophonemics of generative morphology theory. The book aims to answer four questions: 1) What are the inflectional patterns of regular verbs in American and British English? 2) What are the inflectional patterns in irregular verbs in American and British English? 3) What factors influence the use of certain inflectional patterns? 4) How productive is the use of regular and irregular verb patterns?
