From Where to understand basics?

I really want to understand the stock market, but finding the right resource has been a struggle. Either everything is behind a paywall, or the free content is too scattered and confusing. I have a basic understanding, but I need a structured approach to go deeper. YouTube has tons of videos, but they all go in different directions—some focus on technical analysis, some on fundamentals, and some just create hype. I’m looking for a solid, beginner-friendly free resource that explains things step by step. If anyone has a genuine recommendation, please share. I want to build a strong foundation . Any help would be greatly appreciated!
