I’ve read your post ‘How to kill a language’ and I agree with you in relation with the nature of living languages, however, I disagree in relation to the role that language academies play within a language.

It’s quite true that academies tend to be far too conservative and too overjealous about maintaining what they consider to be the purity of a language, but it’s also quite true that they can contribute to maintain the uniformity of a language. Consider the case of the Spanish language academies. With all their historical, political and social shortcomings, these academies have been able to maintain a standard form of Spanish
that is not only unique among the most important languages of the world but also a very remarkable deed if you consider the vast amount of people and countries that have Spanish as their first language.
