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.

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.
