How do you make "Chai tea" the original, please.?

Okay so I hear "Chai Spice tea", "Chai tea", "Chai sweet tea", etc. I don't know which one I've tried but I love it, I absolutely love chai tea or so i think it's just CHAI TEA. So anyways Chai already means tea, so what the heck am i drinking, lol. Well I can taste the cinnamon in it and the ginger and different spices that's all i can pull out of it when i've dranken this unknown tea all i know is that it's called Chai ( ? ) Tea. Thanks, I'd appreciate your responses :-)
