The Local Government Association sent out a list of 100 "non-words" that need to be avoided if officials want to be understood.
The list of banned words includes popular but vague terms like: empowerment, coterminosity, synergies and revenue stream.
The association's chairman says it's time to stop hiding "behind impenetrable jargon and phrases."
In case you're wondering, coterminosity refers to a situation in which two organizations oversee the same geographical area.
