Infinitive Verb. To Do or Not To Do

When you need to say that you want or need to do something you use an infinitive. In other words “to + verb” is an infinitive verb. It also means you do something (use a verb in the sentence) because you want “to do” something else.

Many a times we do things to achieve a certain result. So we tell people that I was doing something to do something else. For example the sentence will be “I was studying to pass the test”. In this example you’ll notice that there is a verb in the sentence that shows the action. That word is ‘studying’. The action was in the past so ‘was’ has been used. This could have been in the present. Then the sentence could have been. I am studying to pass the test. Or past tense – I studied to pass the test. Yet there is another verb after the word ‘to’ which shows why you did the action. This combination of words ‘to’ together with a base verb is called an infinitive. You’ll also notice that ‘to pass’ is not really a verb. It is like a noun. It is like saying – I was studying history. So we come to know that although we are using verbs their use in the sentence is that of a noun. 

Examples:
