...if your academic/professional objectives involve reading documents in Latin. Doubtful, I'd guess...
However, if you like the idea of the stimulating effects involved in acquiring knowledge of another language, a living language should work equally as well!
Have you given any consideration to either Russian or Arabic?
Yes actually, Arabic will be... a bit too stimulating I think. If I recall correctly it has three numbers (singular, plural, dual), the vowels can be omitted from writing and many phrases have four ways of being said depending on the gender of the speaker and the recipient... I think I will pass lol.
Russian's just a bit whack... I don't know. I would actually go for Arabic because more people 'speak' it (let's be optimistic and ignore all the regional dialects).
Oh, my... not at all!
You do have a rudimentary understanding, however: Arabic has both short and long vowels (but English could also be described similarly: bit/beat). The short vowels are not written in Arabic (but are provided for the benefit of learners). Even the quality of the long vowels is only hinted!
A dual form for nouns is no impediment... It's just used when speaking of a pair!
What you will find of academic interest is how vocabulary (nouns, verbs, adjectives, adverbs...) are generated by the pattern in which a 3-consonant root participates. For example, the consonant root k-t-b lies at the core of nearly all words associated withe writing: write, library, desk, author, written, book...
Yes... many colloquial dialects! But, educated speakers communicate quite effortlessly using mildly modified classical (written) Arabic.
As for Russian: New alphabet... correct pronunciation of the written word follows quite well-defined rules (interestingly, the reverse is not quite so exact). In any event... nothing like the disconnect between spelling and pronunciation as exists in modern English (which exists to maintain readable literature over the centuries of spoken language drift).
In Russian, however, you will learn that the admonishment one is taught for English (frequently ignored: never end a sentence with a preposition) is rigidly followed in Russian.
Good luck on whatever language you choose!
Never end a sentence with a preposition
Did you have this clip lying in readiness just for the occasion?
I'm sure my guess will be correct: Swimmerguy will get a kick out of this!
