You could also look into astronomy classes at a local community college. I took an intro to astronomy class at a community college when I was about 18. I think it cost about $4 at the time, and I learned a lot of basics that way. You'll learn about the celestial sphere and constellations. You'll learn basic terminology: right ascension, declination, hour angle, sidereal time, celestial pole, ecliptic, meridian, transit, opposition, conjunction (inferior and superior), quadrature, elongation, occultation, and more. You'll learn the basic geometry of how things are oriented and move in the night sky, lunar phases, orbits, etc. It's a good starting point, and then you could subscribe to something like Sky & Telescope and understand much of the material.
