<p>need not is a modal verb. same as can not, might not.. i posted this q long ago,and begoner cleared it up for me. u might wanna do a search if u want the complete explanation.</p>
<p>by Begoner In English, there are modal verbs such as "can," "will," and "must." These verbs have an identical singular and plural form and do not take an infinitive. For example, you say that "he can run" or "they can run" rather than "he can to run" or "they cans run." Of course, this is common sense. However, "need" is more tricky because it can be used as a modal verb, but it can also be used as a regular verb depending on the context. So you can say that "she needs to wash the dishes" or "she need wash the dishes." The latter usage is becoming increasingly scarce in the English language (generally, only the negative form, as in "she need not wash the dishes," is used). Due to the lack of an infinitive, it is clear that the modal form is being used. But, by ear, you can tell that a construction such as "he needs run" makes no sense. Also, note that the modal "need" has no past tense -- you can't say that "someone needed buy a car."</p>
