Conjugation of English verbs

English is a global language. Speaking and understanding English improves one's chances of obtaining a more prestigious education, finding a job with a good salary, and communicating with others when travelling abroad or on business. Do you want to be proficient in English, both orally and in writing? Уou don't need to learn the forms of verb conjugation if you have the service PROMT.One Conjugator at hand. The grammatical structure of English is simpler than in other languages. However, the use of verb tenses such as Present Perfect, Past Simple and Present Continuous can cause difficulties. The PROMT.One service will help you master the nuances.

English verb conjugation tables

In English, verbs can be regular and irregular. Regular verbs form the past tense and past participle as per the standard rule: with the addition of “-ed”. Irregular verbs have their own unique forms that need to be remembered. There are only about 200 irregular verbs in English, but only about 100 of these are in active use in speech. Novice learners always panic that it is impossible to remember so much information. They are wrong, there is a way: look up the correct conjugation forms of each new, unfamiliar English verb in the PROMT.One Conjugator. The detailed conjugation tables for both regular and irregular English verbs will really help you to learn the language faster.

How do I use the English verb conjugator?

PROMT.One conjugator helps you to conjugate English verbs quickly and easily. Type the infinitive or any other form of any regular verb (like, want, study, improve, stop, travel), irregular verb (be, come, bring, do, buy, drive) or phrasal verb (come back, get out, see off) into the search box and get full information on all tenses, persons, and numbers of the verb. If the word can be used as both a noun and a verb (can, bear, convert, try, building), the Conjugation and Declension service will show you all the options available.

Using PROMT.One you can easily check the plural form of any English noun (map, man, ox, lady, knife, potato, hair). To open the Context section, click any word in the table.
