This is what what said in a Youtube video by a person who speaks several languages fluently by starting from scratch. He said you'll learn ancient Greek faster by learning modern Greek first as it's easier to master, and then shifting those skills and knowledge to learning ancient. Perhaps because modern Greek is more accessible you can practice and live it beyond books, making it faster to acquire. If so, how easy is it for modern Greeks to master ancient Greek? How many Greeks actually do that? Very few English-speakers would bother trying to learn Chaucerian English or even Elizabethan English to greater appreciate Shakespeare. My Latin has improved by learning how all the verbs work first and only then moving onto nouns. I haven't found any kind of timeline for ancient Greek verbs yet, and wanting to try the same approach.
