Infinitives are created by to + verb.
It is important that you can use them correctly in your IELTS speaking and writing or when you use English more generally.
We have already looked at gerunds, which are verbs ending in –ing (which makes them nouns).
Take a look at this paragraph. The infinitives are in red.
To improve my IELTS score, I joined a writing class in a college in my home town. I wanted to make sure that my grammar was as good as it could be. The teachers helped me to understand some complex grammatical points. It is impossible to know everything in a short time, but I improved lot, and I would really like to thank them for what they did. To help me like this was very kind.
All these are being used in different ways. In this lesson we'll examine them further.
The infinitive form of the verb means that it does not take a tense. It is the bare form of the verb, but with 'to' before it.
Here are some examples
A common mistake in writing is to think of it like a finite verb (a verb that has a subject and takes a tense). It does not change its form.
Here is an example of a common mistake with the infinitive:
It took me five hours to reached the destination.
The person has made the infinitive verb, reach, in the past tense. Only the main verb (take in this case) can be given a tense.
This is how it should be written:
It took me five hours to reach the destination.
The table below explains some of their common uses. This is followed by some tables with examples.
When an infinitive is used as a direct object, it is placed after the verb:
They are sometimes used as a reduction of the phrase 'in order to'.
However, note that the use of the gerund in these structures is much more common:
If you do see an infinitive at the beginning of a sentence, it is much more likely to be showing purpose i.e replacing in order to.
If you wish to put two verbs together, then the second verb will need to be an infinitive and / or gerund.
For example, you can't say this:
He hoped see me again.
He hoped seeing me again.
If "hope" is followed by another verb, it needs to be an infinitive:
He hoped to see me again.
Remember, certain verbs should be followed by an infinitive, not a gerund, and some verbs can be followed by either. For example:
I like to swim (verb + infinitive)
I like swimming (verb + gerund)
