When “need” is used as a modal verb, it indicates necessity or obligation. It suggests that something must happen or is required. Unlike the regular verb “need,” which functions as a main verb and requires the auxiliary verb “do” in question and negation forms, the modal verb “need” does not require an auxiliary verb.
1. Forming Sentences with “Need” as a Modal Verb
To use “need” as a modal verb, you generally follow a simple structure:
Subject + need + bare infinitive (base form of the verb)
Let’s look at some examples to understand this better:
Positive Sentence:
- I need to study for the exam.
- She needs to finish her work before leaving.
- We need to buy groceries.
Negative Sentence:
- He doesn’t need to attend the meeting.

2. Using “Need” to Express Necessity

3. Using “Need” to Express Lack of Necessity
“Need” can also be used to indicate that something is not necessary. In such cases, we add the word “not” before the modal verb. Consider the following examples:
