I have been trying to study Korean, knowing how to pronounce the letters/symbols does nothing to tell me what the words mean. Now if the know of a similar language that they can study it would probably help.
That was my point. Korean is something of an isolated language. Most languages have modern cousins, e.g., German and Dutch, any of the Scandinavian languages with one another, all of the Slavic Languages, most of the Romance languages except French. Manx and Erse. Hebrew and Aramaic and Arabic.
