What have we learned about Latin in the last century?

Question

I have studied Latin, but in none of the courses I have taken has there been discussion about any progress in understanding Latin. I do believe — and hope — that classically oriented scholarly activities have produced new insights in the last century, but I am not aware of any such developments.

What is the biggest single step we have taken or the most important new insight we have gained in understanding the classical Latin language after the year 1900? This is a matter of opinion to some extent, but I would like to know what Latinists have achieved and why those achievements are considered important. There are books and scientific articles about Latin, but it is very difficult and time consuming for a non-expert to locate important new ideas and figure out if there is a consensus behind them. I am looking for something that is supported by a broad consensus or is even considered a fact, not hotly contested theories.

Although I probably would enjoy a summary of all developments, I believe this question is more focused when I ask for the single most important development. This question type is somewhat experimental; let me know if you have comments about its broadness and suitability.

Answer 1

It is always difficult to make this kind of charts. I think that the best thing that has been done on Latin over the last decades was to start studying it from a more linguistic point of view. By linguistic approach I mean, among other things, the following:

• Studying Latin within its linguistic environment, i.e. that of the Old Italic languages (Faliscan, Umbrian, Oscan etc.): textual data are richer than before, and we have a better idea of the dialectal zones within the Italic linguistic area. For example, the authenticity of the Fibula Praenestina has been recently proven.
• Studying non-classical periods of Latin; thus, we understand better some historical details of Archaic Latin (such as that of Ennius, one example); we have studied the Vulgar Latin of the Pompeian graffiti, a good source of information about the evolutive processes that were happening on the edge of the Romance era (see here).
• Making sense of what ancient Roman grammarians were saying about their own language. Thus, some obscurities have been nicely explained; see, for example, this brilliant explanation of the meaning of Nigidius' term casus interrogandi. The linguistic analysis of the Appendix Probi is another famous example in this respect.

A disclaimer: I am a linguist, not a philologist, so most probably I am missing many important discoveries made in Latin philology proper.
