Irregular verbs do not follow the standard patterns of conjugation. The following table contains the most common irregular verbs in modern English. Some verbs have regular and irregular conjugations; alternatives are separated by slashes (/). The infinitive form corresponds to the present tense. The 3rd person singular adds an "s" for the present tense, but "do", "go", and verbs ending in "ch", like "teach", add an "es".

Regular Verbs

English regular verbs change their form very little (unlike irregular verbs). The past tense and past participle of regular verbs end in -ed, for example:

work, worked, worked

But you should note the following points:

1. Some verbs can be both regular and irregular, for example:

learn, learned, learned
learn, learnt, learnt

2. Some verbs change their meaning depending on whether they are regular or irregular, for example "to hang":

regular hang, hanged, hanged to kill or die, by dropping with a rope around the neck
irregular hang, hung, hung to fix something (for example, a picture) at the top so that the lower part is free

3. The present tense of some regular verbs is the same as the past tense of some irregular verbs:

regular found, founded, founded
irregular find, found, found

English verbs have the base form (Infinitive), the simple past and the past participle. For most of the verbs (regular verbs), the simple past and the past participle are spelled the same and are created by adding -ed to the base form. However, there are many irregular verbs in English language which do not match to this pattern. Those verbs are mostly unpredictable, it is hard to derive them on the fly as you talk. There are some patterns among them (spring-sprang, drink-drank,...), (blow-blew, know-knew,...) but it is still hard to use those patterns as rules. The only way to learn irregular verbs is to memorize them. Take Irregular verbs spelling quiz.
