Your question is really vague, but I’ll try my best.
“Patriarchy” means “a system of society or government in which men hold the power and women are largely excluded from it.” That’s the kind of society we live in right now.
Honestly, I’m not an academic scholar of feminism so I don’t have all the tools and language to be able to adequately explain all the ways in which the patriarchy affects pretty much every aspect of our lives, but lots of other people have written thoughtfully on it and a Google search will set you straight if you’re confused about any of the concepts.
