requérir

The French verb "requérir" means to require, to request formally, or to call for something, often in an official, legal, or formal context.

Meaning:

• To formally ask or demand something, especially in legal or administrative situations.
• To need or necessitate something.

Examples:

• Le tribunal requiert la présence du témoin.
  (The court requires the presence of the witness.)
• Ce travail requiert patience et expertise.
  (This work requires patience and expertise.)

Synonyms and Differences:

• Demander: Means "to ask" or "to request" but is more general and informal.
  "Demander" can be used in everyday situations, without an official tone.

• Exiger: Means "to demand" or "to require" more strongly, implying obligation or insistence. Stronger and sometimes harsher than requérir.

• Nécessiter: Means "to necessitate" or "to require," focusing on the need or essential nature of something rather than a formal demand.

• Solliciter: Means "to solicit" or "to request" politely, generally used for applications or formal requests but with a softer tone than requérir.

Usage note:

Requérir tends to appear in formal, legal, or written French. It is less common in everyday speech, where demander or exiger might be preferred depending on the tone.
