To ask (someone) for something; to request.
"She did not require a formal invitation, so she simply knocked on his door when he was home."
In plain English: To require means to need something in order to get by or succeed.
"The job requires you to be available during the evenings."
Usage: Use require when stating that someone must provide or do something, often implying an official obligation rather than a simple preference. It is stronger and more formal than synonyms like ask, which suggests only a polite inquiry without guaranteed compliance.
The word came into English from the Old French requerre, which was borrowed from the Latin requirere. While it originally meant to "seek" or "ask for," its meaning in modern English has shifted specifically to mean a demand or necessity.
