Infinitive with to

Additional Grammar Notes:

• The infinitive has two forms in English:

1. WORK is the form which is given in a dictionary. You have seen this used in present simple questions and negatives, for instance: Do you work?, I didn't work , and after the modal verb CAN.
2. TO WORK you should already be familiar with the infinitive with to used after some verbs such as want and would like, for instance: I want to come with you.

! The infinitive of purpose is only used to express a (+) reason. To express a (-) reason we use in order not to or so as not to. For example: We took a taxi so as not to be late.
