Demand vs. Require – Which is Correct?

While both demand and require express a need, their core distinction lies in agency and intensity. Demand implies a forceful, often non-negotiable insistence, typically from a position of authority or strong expectation. Require suggests a necessity or obligation, often impersonal or based on rules, without the same forceful tone. Both are correct, but their usage depends on the specific context and the nature of the need or expectation.

Demand or Require – Which is Correct?

Both “demand” and “require” are correct verbs in American English, but they carry distinct connotations that make them non-interchangeable in many contexts. The primary distinction lies in the implied level of urgency, authority, and the nature of the necessity. Demand conveys a strong, often assertive, and sometimes confrontational insistence for something, implying a right or an expectation that must be met. It often suggests a lack of choice for the recipient. Require, on the other hand, indicates a necessity, obligation, or a condition that must be fulfilled, often in a more neutral or formal tone. It suggests that something is essential or mandatory rather than forcefully insisted upon.

The Best Trick to Remember the Difference

Think of the “Authority/Agency Test.” If the need comes from a person or group exerting their will or authority, choose demand. If the need comes from a rule, a situation, or a less personal obligation, choose require. For example, a customer might demand a refund (personal agency), but a job might require a specific degree (impersonal necessity).

Word	Part of Speech	Meaning	Example
Demand	Verb, Noun	(Verb) To ask for something forcefully, insisting on it; to need something urgently. (Noun) An insistent and peremptory request, or the desire for goods/services.	The union leaders demanded better working conditions.
Require	Verb	To need something; to make something necessary; to obligate.	This recipe will require two cups of flour.

How to Use Demand

The word “demand” is used when there is a strong, often non-negotiable, insistence or a very clear, urgent need. As a verb, it implies a forceful request or a state of needing something immediately. As a noun, it refers to the act of demanding or the total amount of goods or services consumers want. The tone of “demand” is typically assertive, sometimes even aggressive, and it often comes from a position of power, authority, or a strong sense of entitlement.

Example 1: The customer demanded to speak with the manager after a frustrating experience.

Example 2: High-quality software engineers are always in high demand.

Etymology of the word Demand

“Demand” comes from the Old French demander, meaning “to ask, inquire, request,” which in turn derives from the Latin demandare, meaning “to entrust, commend, order, demand.” The Latin root is a combination of de- (down, away) and mandare (to order, command, entrust). Its meaning has evolved to emphasize the forceful or authoritative aspect of asking.

The historical connection of ‘demand’ to ‘request’ highlights the importance of precise word choice, a topic further explored in Request vs. Requestor.

How to Use Require

“Require” is used to express a necessity, an obligation, or a condition that must be met. It often implies a more formal or impersonal stipulation than “demand.” Something that is required is essential, mandatory, or prescribed by rules, laws, or circumstances. The tone is generally neutral, objective, or authoritative in a regulatory sense, rather than personally insistent. It focuses on the essential nature of what is needed.

Example 1: All applicants are required to submit a cover letter and resume.

Example 2: The project will require extensive research and collaboration.

Example 3: Safety regulations require all workers to wear hard hats on the construction site.

Etymology of the word Require

“Require” originated from the Old French requerre, meaning “to seek, demand, ask,” which came from the Vulgar Latin requaerere, a variant of the Latin requirere. The Latin requirere means “to seek, search for, ask for,” from re- (back, again) and quaerere (to seek, ask). Over time, its meaning shifted from simply “to ask for” to “to need as essential” or “to impose as an obligation.”
