(I hope this is on-topic.)
I am deciding which language to learn next. I am a native Spanish and fluent English speaker. My three options are Latin, Italian, and French. I would like to receive your insights on which option is the optimal, given my current knowledge, and the following criteria:
- efficacy: how well I can learn it, primarily in reading and writing, but ideally in speaking too;
- speed: how quickly I can learn it;
- stepping stone to learning a further language.
If you think there is another criteria of relevance, please mention it. Surely, the "usefulness" is also important, but that is a much more personal aspect, which I am not including, as it might disqualify this as primarily opinion based.
Important: Assume I would allocate the same level of time to whatever option I take, and that I have access to the required books, videos, and other online tools. Notice that I plan to learn the language by myself, and I do not live in countries where these languages are spoken, nor plan to move to learn them (not that Latin is spoken anywhere on a regular basis anyway).
