1. The specialized, often complex and jargon-filled language used by federal government agencies and officials.
Usage: informal; often used critically to describe unnecessarily complicated bureaucratic language

Examples

• The tax code is written in such dense federalese that most citizens need a lawyer to understand it.
• The agency's memo was full of federalese, making it nearly impossible for the public to grasp the new policy.
• Critics argue that federalese obscures rather than clarifies government intentions.
• The Plain Language Act was designed to reduce federalese in official government documents.
• Even experienced civil servants sometimes struggle to decode the federalese in interagency communications.
