Learn 100 English irregular verbs through a fun adventure with Gramm, the charming cat, and Verby, his cheerful bird companion. In Irregular Verbs with Gramm, you'll travel through 10 memorable locations across Britain while learning the most common irregular verbs step by step. Explore places from mysterious Stonehenge to historic Greenwich and turn English verb practice into an engaging game. LEARN IRREGULAR VERBS STEP BY STEP Start with the most frequently used verbs and gradually move to less common ones. Instead of memorizing a long irregular verbs list, you practice each verb through short interactive challenges designed to help you recognize and remember all three forms. Practice the base form, past tense, and past participle — for example: go, went, gone. Repeated exposure helps you build confidence with English verb forms and remember the verbs you are most likely to use first. KEY FEATURES • Learn 100 common irregular verbs — Build useful English vocabulary by studying high-frequency verbs before moving on to less common ones. • Practice all 3 verb forms — Work with the base form, past tense, and past participle until the three forms become familiar. • Four learning stages per level — Practice with cards, multiple-choice quizzes, recognition exercises, and timed activities. Each stage changes the task so you do more than simply memorize a list. • Smart repetition — Mistakes are tracked during practice, helping difficult irregular verbs receive more attention as you continue learning. • Hear every verb pronounced — Listen to each verb form and connect spelling with sound. Pronunciation practice supports listening comprehension and recall. • Learn through a game — Progress through an adventure with Gramm and Verby instead of working through a traditional vocabulary drill. Complete challenges and unlock new levels. • Explore famous locations — Finish levels to unlock photos, achievements, and stories about landmarks across Britain. BUILT FOR IRREGULAR VERB PRACTICE Irregular Verbs with Gramm is designed for learners who want a focused way to study English irregular verbs without unrelated lessons. It can help beginners build a foundation, students review important verb forms, and more experienced learners refresh past tense and past participle forms they already know. The app focuses on practical repetition: see the verb, hear it, recognize its forms, make a choice, and meet it again later. Use it for daily English vocabulary practice, test revision, or learning a few more irregular verbs each day. If you are looking for an irregular verbs game, an interactive way to practice English verbs, or a more memorable alternative to a standard irregular verbs list, join Gramm and Verby on their journey. By the end of the adventure, you will have practiced 100 English irregular verbs and all three forms of each verb. Start your journey, improve your English vocabulary, and see how many irregular verbs you can master! FREE LEVELS AND PREMIUM Levels 1–2 are free.
