Why Do We Use Bare Infinitive Forms with 'Need' in English?

Have you ever come across the phrase "Need be" and wondered why it is used this way in English? In this article, we will explore the grammatical reasoning behind the use of bare infinitive forms with the word "need" and why it is considered a semi-modal verb by many grammarians.

The Role of 'Need' in English Grammar

When discussing the phrase "need be," one must understand that "need" can serve as both a regular verb and a semi-modal verb. This dual nature often leads to confusion among English learners and writers.

Understanding Bare Infinitive Forms

A bare infinitive is a verb form that is used in English without an inflection and with no other indicator of number or person. For example, "to eat," "to play," and "to sleep" are all bare infinitives. These verb forms are very versatile and allow for the creation of new verbs from nouns, such as "to parent." However, not all grammarians agree on the status of bare infinitives in English grammar.

Why 'Need' is Considered a Semi-Modal Verb

Grammarians generally agree that in certain contexts, "need" is used as a semi-modal verb. This is exemplified in the following sentence:

No adjustment need be made.

The phrase "need be" is a construction where "need" takes the bare infinitive "be" as its complement. This usage is similar to how modal verbs are used in English, such as "should," "must," or "can." While "need" is not officially listed as a modal verb, many grammarians treat it as such.

Historical Context of Bare Infinitives with 'Need'

The confusion around the use of bare infinitives with "need" arises because English has a complex system of verb forms and doesn't always adhere to the traditional Latin paradigms of conjugation. Some grammarians assert that "need" is more akin to a modal verb in such constructions. My own view is that English could benefit from a more contemporary approach to grammar, one that better aligns with modern usage.

Common Misconceptions and Realizations

Many people incorrectly believe that "need" should be followed by the base form of the verb (e.g., "need to go"). However, in the construction "need be," the bare infinitive is used, and this is considered a more archaic or formal usage. It is not common in everyday speech, except in very formal or literary contexts.

Practical Usage and Recommendations

If you are aiming for a more natural and accessible tone in your writing, it is generally safer to use the modal construction, such as:

No adjustment is required.

or

No adjustment is needed.

Such constructions are more common and are understood by a wider audience. However, if you are writing in a formal or literary context, you may use "need be" to convey a more archaic or formal tone.
