Languages that are formally very close to each other and mutually intelligible (their speakers have no difficulty in understanding each other), yet for political reasons are considered to be separate languages, include the following:
d. Serbian and Croatian
C.) draw pictures or diagrams
Just a couple ideas for you, if you need more let me know. If there are specific words you need to know for a test or something like that, try creating flashcards to practice. You can create them with physical cards, or if you prefer, there are lots of free apps you can get or websites to create virtual flashcards. A popular website for creating flashcards is Quizlet. You could also try Duoling, I believe it has a latin course. It is a free app, and I believe they are also a website.
