We have had a number of questions about sound changes, asking for the history of specific changes. See this one, for example: asking about the change from Latin benedictionem to French beneiçon. Often, as the original poster of that question observed, the process can be explained by a series of steps of just one sound correspondence. As far as I know, each sound change is only productive for a certain period of time in a language. Of course, different changes may be occurring simultaneously, so overlaps of these periods are expected.
I am looking for something more general: a diagram — probably a tree-shaped one — that shows the development from Latin into the Romance languages. The diagram must meet the following requirements:
- Shows at least two of the major six Romance languages: Spanish, Portuguese, French, Italian, Romanian and Catalan.
- Each branch shows the history of the language from Vulgar Latin to the present day.
- Each branch has the sound changes and their respective (approximate) periods annotated.
- For each language, any variety can be chosen, as long as it remains the same throughout the diagram.
Is there some book, site, whatever, where one can find such a diagram?
