Reason I ask is I have become very interested in the origin of languages over the last year or so (partially because of Covid). I've been learning German and French for a while now and I find the most difficult parts of learning these languages to be the grammar. I'd like to find a hierarchy of grammar for related languages, and see if there are some patterns that filter down through the child languages. I have a Latin textbook (probably need to dust that off), and am very interested in how these languages (Romance and Germanic) are all stitched together.
