The past participle of an irregular verb can also function as an adjective: a broken dish. Be careful never to add a helping verb to the simple past form of an irregular verb- I have broke your dish is an embarrassing confession in more ways than one. The compound verb have broken is so called because we've added a helping verb ( have) to the main verb's past participle ( broken). We use the past participle, broken, to form compound verbs in sentences like I have broken your dish. The simple past tense is broke, which we use in sentences like I broke your dish. Let's get back to the irregular verb break. And then there are a few really weird ones, like go: its past participle ( gone) is recognizable enough, but its simple past tense is a strange new word ( went). Still others, like break and sing, change to form the past tense ( broke, sang) and change again to form the past participle ( broken, sung). Others, like feel and teach, become modified versions of themselves ( felt, taught) to form both the past tense and the past participle. Some irregular verbs, like let, shut, and spread, never change, whether present or past. They form the simple past tense and the past participle in any number of unpredictable ways. A regular verb's simple past tense and past participle are always identical. We call a verb regular when we add ed ( want ed, look ed) or sometimes just d ( create d, love d) to form what are called the simple past tense and the past participle (see third and fourth paragraphs below). English verbs are either regular or irregular.
