English Irregular Verbs

Do you know how many irregular verbs there are in English? According to this website, there are as many as 620! But luckily, far fewer are the common ones. 211 of them are listed on this UsingEnglish.com page. And they are listed in two ways that would help an English learner a great deal. First, horizontally, the list clearly shows how most every English verb has only five forms, which reminds people how easy it is to learn English vis-a-vis some other languages that have a whole dictionary just for their verb conjugations. Two, vertically, every headword, i.e. the base form of verb, is clickable to reveal the pattern of the conjugation across the verb forms as well as what other verbs share in this pattern. So, this is quite a useful online tool, if you ask me.
