  • Something required is needed or must be done.
  • It implies necessity and often obligation.
  • Used in formal and informal contexts for rules and needs.

Overview

The word 'required' is an adjective that indicates something is essential, necessary, or mandatory. It stems from the verb 'require,' meaning to need or demand something. When something is described as required, it implies that it cannot be omitted or bypassed; it's a prerequisite for achieving a goal, fulfilling an obligation, or meeting a standard.

Usage Patterns

'Required' is often used to specify conditions, qualifications, or items that are indispensable. It frequently appears in contexts related to rules, regulations, job applications, educational programs, and instructions. It can be followed by 'to' + infinitive (e.g., 'You are required to complete this form') or by a noun phrase (e.g., 'A valid passport is required').

Common Contexts

  • Education: 'A bachelor's degree is required for this position.' 'These are the required textbooks for the course.'
  • Employment: 'Applicants are required to have at least five years of experience.' 'Wearing safety goggles is required in this area.'
  • Legal/Official: 'A signature is required on all official documents.' 'Proof of identity is required before entry.'
  • General Necessity: 'Water is required for survival.' 'Patience is a required quality for teaching.'

Similar Words Comparison

  • Necessary: Similar to 'required,' but 'necessary' often implies something is needed to achieve a specific result or outcome, whereas 'required' can carry a stronger sense of obligation or demand. 'To pass the exam, studying is necessary.' vs. 'To pass the exam, the following modules are required.'
  • Mandatory: This word is a very close synonym, emphasizing that something is compulsory and must be done by law or rule. 'Mandatory' often feels stronger and more official than 'required.' 'Attendance at the meeting is mandatory.'
  • Essential: This highlights something as fundamentally important or necessary. It's a core component. 'Oxygen is essential for life.' 'Good communication skills are essential for this role.' While often interchangeable with 'required,' 'essential' focuses more on the fundamental nature of the item/quality rather than a strict rule.
  • Obligatory: Similar to 'mandatory,' indicating something that is required by a moral, legal, or social obligation. 'It is obligatory for citizens to vote.'
