Latin can be useful when it comes to memorizing lists, as the derivation can help with the definition of the word. Greek is also useful. I would not recommend a course in Latin though, since all the grammar one would learn would be wasted, and you'd miss out on half the root words that are derived from greek. My school had a course in greek and latin for scientific terminology; essentially it focused on root words, identifying them, synthesizing terms with them, and explaining how the derivation helps show you the definition. No grammar was taught. I really enjoyed this course, and we covered way more root words than the latin courses, so I found it way more useful.
