Gaudeamus Igitur

It would seem that at least one of the local authorities in England is intent on making its documents intelligible to all people by banning Latin words and phrases such as ‘inter alia', ‘ad hoc', ‘per capita' and, in one case, even ‘via'. Apparently, some people don't know the meaning of these phrases – and presumably don't know how to look up the meanings. Why can't councils concentrate on what they are supposed to be doing, like providing an education?
