So, since economy is never something "created" but rather adapted from the past working stuff, and we are pretty much still monkeys, the more of a certain currency there is on the market, the less value is usually given to it.
When the currency loses it's value merchants will increase the prices to keep up their quality of life, eventualy cascading in everything on the country, from supermarkets to exterminators, being more expensive.
This is the basic gist of it, a lot of factors can influence inflaction, including monopolies, oligarchies, and pure bad faith from merchants. But getting into that would be too much for a 4chan post, so google can be your fren from now on.
