Verbs are often a problem area for students of English as a second or third language.
As such English is quite easy when it comes to regular verbs as you only have the -ed ending (talked, walked…) for past actions, the ing-form for continuous action (and some other cases) and the s-form for the third person singular in the present tense. That only amounts to three different verb endings; -s, -ed, -ing. The problems come with how to use these verb endings, and then, of course, you have all the irregular verbs.
Irregular verbs are common and frequently used. You should learn the most frequent first. (There are more than 200). There are lists in books and on the internet. I will include a few links here below. When you go wrong with an irregular verb. I strongly suggest that you take some extra time to learn the correct form. This is an effecctive use of your study time and will quickly give you and improved proficiency.
