sûrs

Sûrs is the masculine plural form of the French adjective sûr, meaning certain, sure, or safe. It agrees with masculine plural nouns; the feminine singular is sûre, and the feminine plural is sûres, while the masculine singular is sûr. In everyday use, sûr can express confidence about a fact (Ils sont sûrs de leur réussite), safety or reliability (un produit sûr, des plans sûrs), or certainty in judgment (c’est sûr).

The adverb derived from sûr is sûrement, which can mean surely or probably depending on context. The related noun sûreté denotes safety, security, or reliability, and appears in phrases such as la sûreté nationale or la sûreté des personnes. In legal or institutional language, the term sûreté is sometimes found in the names of police or security agencies, for example Sûreté du Québec.

Etymology: sûr comes from Latin securus and entered Old French as seur, evolving into the modern form with the circumflex placed over the vowel in sure/sûr and related derivatives. The circumflex indicates a historical change in spelling and pronunciation that occurred over time in French.

Usage notes: sûr has multiple synonyms depending on sense, including certain, certain, fiable, and sûr de soi in appropriate contexts. The choice among these depends on whether the meaning is about certainty, safety, or trustworthiness. As a result, sûr and its forms are common across everyday French, media, and formal writing, often appearing in contexts describing risk, confidence, or verification.
