ELI5: What, exactly is capitalism?

I have googled it, trust me. I just don't understand it, no idea why. Can anybody help me out here?

Edit: sorry about the comma in the title, lol.

Three main factors (simplified for this post) make capitalism:

* private citizens own the businsses, not the government 

* goods are sold for profit, not given away at cost

* markets decide the prices of things, not cartels or governments

Now, as with most things in life, in practice not everything is black and white.  Even in a "capitalist" nation like the USA, the government owns some businesses and sets some prices.  Other nations like China may be in even more of a gray area.  But these are the main factors.
