" Need" as a modal
When can we consider "need" as a modal ? I've read about it in a book which cosnsiders "need" as a modal if it is not followed by "to" and otherwise it is considered as a main verb. Is this true?
Yes, Need is used as Modal.
Need behaves as a modal verb, like can, could, must should, etc. It has the same forms as modal auxiliary verbs: the third person singular has no "s", questions and negatives are made without do. In this format, need is followed by an infinitive without to:
You needn't bother to change the sheets. I'll sleep in them later.
Need I lock the door when I leave? ~ No, you needn't. Sam will be home soon.
In this sense, we are talking more about obligation and giving permission to someone not to do something. Note also that as a modal verb it is most commonly used in negative sentences and sometimes in questions.
Now, your question.
It is truely said:
When need is used as modal, there comes verb in the basic form (bare infinitive).
When need is used as main verb, verb comes with to.
