This video will help you see relationships among various types of irregular verbs in English. The key to understanding irregular verbs is to look for and notice the patterns. Verbs like grow also have an N ending, but it's not an E-N ending. For example, verbs like grow shift vowel sounds in the past and the past participle. They also take on the W-N ending in the past participle. Let's look at some examples. Blow, blew, blown, fly, flew, flown, grow, grew, grown, know, knew, known, throw, threw, thrown. Now an interesting one, a variation on this would be the verb show. Instead of doing the E-W ending in the past, we show follows an E-D regular verb ending in the past show, showed, shown. Now the last two are a little bit different in that they don't end with O-W-N, they end with A-W-N. And that's basically because in the original base form you already have an A-W, but it follows the same pattern in the past, draw, drew, drawn, withdraw, withdraw, withdraw.
