Verb Forms: Main Verbs

English verbs come in several forms. For example, the verb to sing can be: to sing, sing, sang, sung, singing or sings. This is a total of 6 forms. Not many, considering that some languages (French, for example) have more than 30 forms for an individual verb. English tenses may be quite complicated, but the forms that we use to make the tenses are actually very simple! With the exception of the verb to be, English main verbs have only 4, 5 or 6 forms. To be has 9 forms. Do not confuse verb forms with tenses. We use the different verb forms to make the tenses, but they are not the same thing.

At school, students usually learn by heart the base, past simple and past participlepresent participle3rd person singular present simple by heart - for another very simple reason: they never change. The present participle is always made by adding "-ing" to the base, and the 3rd person singular present simple is always made by adding "s" to the base (though there are some variations in spelling).
