What is an Infinitive in English?

The infinitive is the basic form of a verb. It is the verb in its simplest form, without any changes for tense or subject.

• Sometimes it has to before it (e.g., to eat, to sleep).
• Sometimes it does not have to (على سبيل المثال،, eat, sleep).

Knowing when to use to and when not to is an important part of English grammar.

الأسئلة الشائعة

What is the main difference between 'to + infinitive' and the bare infinitive?

The main difference is the words that come before them. You use to + infinitive after many regular verbs (like want, need) and to show purpose. You use the bare infinitive (without to) after all modal verbs (like can, must, should).

Can I use 'to + infinitive' after 'can' or 'must'?

No, you cannot. Modal verbs like can, could, must, should, will, would, may, ، و might are always followed by the bare infinitive (the verb without to). على سبيل المثال،, I can swim, ، وليس I can to swim.

How is this grammar point tested in the A2 Key (KET) exam?

In the A2 Key exam, you might see tasks where you need to complete sentences or correct mistakes. For example, you may need to choose the correct form of a verb after a modal (e.g., You must [study/to study]) or after a verb like want (على سبيل المثال،, I want [go/to go]). Pay close attention to the verb before the blank.

Are there any verbs that can be followed by both 'to + infinitive' and another form?

Yes, some verbs can be followed by different forms, but for A2, focus on the basic rules. For example, like can be followed by to + infinitive (I like to swim) أو verb-ing (I like swimming). Both are often correct, but the meaning can be slightly different.
