A need is a desire for something. People need food, water, and shelter, and these things can only be provided by other people. Without these basic necessities, they are in need of help. However, these basic necessities aren’t always available. In these cases, the need is expressed as a wish, and this can be a good way to help someone in need. The need for food, water, and shelter is often felt as a feeling, but it can also be a need for physical comfort.
Needs are essential for life, and this is especially true for our health. We need food, water, and shelter to stay healthy. But we also need access to information. It is essential for our mental and physical health. We can’t live without the Internet, or even cell phones. But we need a computer to communicate with our loved ones. And we need to have access to public places where we can go for a walk, even if it’s just a short distance away.
Need is an important word in writing. It is often used as an auxiliary verb or as a main verb. In its main role as an auxiliary verb, it agrees with the subject of a sentence and takes the place of the following verb. In many constructions, need combines with do or is a supplementary verb, such as want. In many cases, though, need is more appropriate when describing an obligation or a need.
In the American Heritage Dictionary, fifth edition, need behaves as a modal verb. It agrees with the subject and takes the form of the infinitive without to. In its main role as an auxiliary verb, need does not combine with do. It is often used in sentences expressing obligation or necessity. But in other constructions, it is not a necessary part of a sentence. It is an auxiliary verb. The main function of need is to indicate obligation or a need.
In a sentence, need behaves like an auxiliary verb. In a modal clause, it agrees with the subject and takes the place of the following verb. In a complex sentence, need is the auxiliary verb. It is also used in a situation where something is needed, such as a food or a drink. If a food is in demand, the need can be a symptom of a more pressing need.
When used as a modal verb, need takes the auxiliary form of do. It does not agree with a main verb, and it takes the auxiliary form. For example, when need occurs in a phrase, it uses the auxiliary form of need. It has the same meaning as the auxiliary verb. In British English, need is not used in the same sentences as need, but it may be a subordinate clause, but it has the same meaning.
