Tenses

Verb Tenses

There are 12 verb tenses in English. The verb action can take place in the past, the present or the future. There are usually word clues that give a guide as to when the verb action occurs. Within each of these times, there are four different situations that occur. Simple tenses occur at a point in time, or on a repeated or habitual basis. A progressive or continuous tense indicates that the action takes place over time and these tenses always use part of the verb “be” as the first part of the verb phrase and end with the main verb + ing. A perfect tense always uses part of “have” as the first part of the verb phrase and ends with the past form of the main verb. A perfect progressive tense starts with the relevant part of the verb “have” followed by “been” and ends with the main verb + ing. If you remember these basic rules, you can always identify the verb tense being used, or use the verb tense you need without having to continually refer to a text book or table. Meanwhile, a chart like the one given here, can provide a quick and easy reference until you feel comfortable using the various verb tenses. Also pay attention to the time clues in the following chart; while some of them can be used with more than one verb tense, they do restrict the number of possibilities and help you to understand which verb tense is being used, or which verb tense you should use.
