My What Long Words You are Using

In my work we are striving to communicate in language that everyone will understand - y'know clear, simple, concise. We're fond of the Plain English campaign and attempt to rid our communications of jargon and acronyms. Our aim is that even our ESOL (English for Speakers of Other Languages) learners will understand what we're on about (not always possible of course but pictures help sometimes).

In my MA they are striving to communicate in language that academics will swoon at - y'know clever, complicated and verbose. They're fond of long, obscure words, that only appear in the biggest dictionaries. They claim its to aid higher understanding. I consider my self fluent in English but its hard reading, let alone understanding. Pictures are unheard of, and probably would be of little help.
