Okay, imagine you've got two types of government: a democracy, where people vote to decide who's in charge, and a dictatorship, where one person has all the power and makes all the decisions.
Now imagine if a country had a government that was a mix of both - some parts of it were democratic, like people voting for their leaders, but other parts were more like a dictatorship, where one person had a lot of power and could make decisions without asking anyone else.
That kind of government is called a "hybrid regime," because it's a mix of two different types of government. It's not always easy to tell exactly what kind of government a country has - sometimes it's somewhere in between two different types.
Hybrid regimes can be good or bad, depending on how they're run. Sometimes they're more stable than pure democracies or dictatorships, but other times they can be less fair and less effective.
