Need is used both as a principal verb and as an auxiliary verb.

Need as a principal verb

When used as a principal verb need means ‘require’. The principal verb need is followed by an infinitive with to. It has the forms needs and needed.

I need more time to finish the job.
We have got what we needed.
We need to find a way out.
You need to talk to him.

As an auxiliary verb

As an auxiliary verb, need remains unchanged whatever be the person or number of the subject. The auxiliary need is common in questions and negative sentences.

You need not ask my permission.
She need not wait any longer. (NOT She needs not wait any longer.)

The negative adverb hardly is often used with need.

Need is also used with only.

Need can be used in questions.

If the answer is in the negative, say ‘No, you need not’. If the answer is in the positive, say ‘Yes, you must’.
