This course has been written for people learning English at different levels and who want to consolidate or supplement their knowledge of irregular verb forms. In fact, English regular verbs generally do not pose much of a problem to learners as long as they know the basic rules about how they function and how to form past simple and past participle forms.

Irregular verbs forms, however, must be learnt by heart, as they have their own rules.

The 300 English irregular verbs discussed in this course are divided into three groups. The first contains those irregular verbs where the infinitive form, the past simple form and the past participle form are different, as well as those irregular verbs where the past tense form or the past participle form is the same as the infinitive. The second group contains irregular verbs where the past simple and the past participle forms are the same, and the third group contains irregular verbs where the infinitive, past simple and past participle forms are identical in spelling, though in a few cases they do differ in pronunciation.

The use of each irregular verb and its forms is illustrated by several example sentences, making it much easier to remember the forms in context.

The topic on irregular verbs presented in the course will help to enrich and expand both the practical and correct use of them.
