What does consensus mean?
Consensus refers to a general agreement or shared judgment reached by a group after discussion or deliberation. Unlike a simple majority vote, consensus implies that the group's members broadly accept a decision — not that everyone is equally enthusiastic, but that no one is fundamentally opposed. The word appears most often in formal contexts: politics, science, business negotiations, and international affairs. One might speak of a political party reaching a consensus on policy, or of a scientific consensus supporting a theory, meaning the prevailing view held by most experts in the field. The term carries a positive connotation of fairness, inclusivity, and collective legitimacy, which is why consensus-based decision-making is valued in organizations seeking unity rather than division. Derived from Latin, where it meant agreement or harmony, the word entered English in the seventeenth century. It remains an essential term for describing how groups settle on shared conclusions.
nounA general agreement or collective opinion reached by a group, typically after discussion or deliberation.
- General agreement or collective opinion among a group, especially one reached after discussion.
- (Politics/decision-making) A decision-making process or outcome in which all members substantially agree, without necessarily requiring unanimous enthusiasm.
"After hours of debate, the committee finally reached a consensus on the budget proposal."
"The committee struggled to reach a consensus on the new budget proposal."
"There is a broad scientific consensus that human activity is driving climate change."
The plural is rare; consensus is usually treated as uncountable, and writers prefer singular constructions such as 'a consensus exists.' When pluralized, consensuses refers to multiple distinct agreements across different groups or issues.
"Different committees arrived at different consensuses on the question."
Despite its popularity in meetings everywhere, 'consensus' technically means more than majority agreement — it implies everyone can live with the decision, even if not everyone loves it.

Etymology of consensus
Consensus derives from the Latin verb consentire, meaning 'to feel together' or 'to agree,' formed from the prefix con- ('together') and sentire ('to feel' or 'to perceive'). It entered English in the early seventeenth century, initially carrying senses of harmony and accord before narrowing toward its modern meaning of collective agreement. English shares this root with related borrowings such as consent, concentric (via centrum), and sense itself, all ultimately tracing back to the same Latin verb of feeling and perceiving.

How consensus is actually used
Consensus is used primarily in formal and professional registers — politics, science, business, and diplomacy. It carries a neutral-to-positive connotation, implying fairness and collective legitimacy. The phrase 'general consensus of opinion' is often criticized as redundant since consensus already means agreement of opinion. Consensus does not strictly require unanimity; it usually denotes substantial agreement that allows a group to move forward.
