Common Mistakes When Using Agreement Synonyms

Calling a casual promise a contract

A contract is written and legally binding, so a friendly promise between friends is better called a pact or an understanding.

Using treaty for small agreements

Treaty belongs to countries and large organisations; using it for a classroom plan sounds comic rather than formal.

Confusing consensus with a simple vote

Consensus means the group genuinely accepts a shared decision, not just that the majority outvoted the rest.

Using settlement when nothing was disputed

Settlement ends a disagreement, so a brand-new friendly plan is an arrangement or a deal, not a settlement.
