How it's used

Describes social norms or linguistic habits that lack formal documentation but are universally understood. It carries a sense of collective agreement that has evolved naturally over time rather than being imposed by an authority. Use this to explain why certain behaviors or word choices are expected even when no written rule exists.

Examples

This title is established by convention; everyone is used to calling it that.
Why do it this way? Actually, it is just a matter of common practice.

Common mistake

Learners often mistake this for a formal legal requirement or a strict law, but it specifically refers to informal, unwritten social contracts. Do not use it for rules that are explicitly stated in a handbook or contract.
