One good resource that's often recommended on online photography boards (so take it for what it's worth) is a book: Bryan Peterson's Understanding Exposure. I'd also throw on that pile, Peterson's composition basics book, Learning to See Creatively. Both of them break down the basics of photography into clear prose that seems to ignite that "ah-ha!" moment in a lot of readers.
And, to me, most importantly, Learning to See Creatively is mostly taste-agnostic in describing the basics of composition. Rather than teaching "good" vs. "bad" composition or "strong" vs. "weak" composition, a particular compositional choice is explained through its basic effects. There is no "you must adhere to the rule of thirds", more "here's the rule of thirds; and here's what the effect of using it is."
I think this taste-agnostic aspect of Learning to See Creatively is much more important for a beginner who has yet to establish their own personal taste and voice. It lays out the tools you can choose to use for composition, rather than inadvertently getting you to imitate the taste of the author, as more advanced composition books almost inevitably can.
I would also say that the other much-neglected part of how to learn photography is to simply look at a lot of photography. How you form your own style and taste is, in part, by how you react to works that you see. Musicians listen to music; a director sees a lot of film; a chef has tasted a lot of dishes; authors read a ton. Photographers look at photos. If you want to form your own style and your own voice, it can help tremendously to be aware of what other photographers have done and are doing. Art may be able to exist in a vacuum, but it grows ever so much better when it's fed things.
