How does anyone remember all these genders - skirts (rock) are male and trousers (Hose) are female!

I dont know if its a fault on duolingo but i am doing possessive pronouns and when i complete a lesson it also updates my progress on nom pronouns! Is the any way to reset a group of lessons?

I'm very new at this, what is the difference between Ihre and Ihr, don't they both mean her? Or am I mistaken?

Just memorize them, it's easier than a pattern that only half works.

Isn't "hose" masculine? I was going for Ihr Hose...

Thank you so much

Isn't Ihre for yours or theirs? I thought Seine was hers.

You can use either Hosen (plural) or Hose (singular) here. Is Hose also a pluralised word on its own, like pants and trousers? In that case, what's the point of having Hosen if you'd just use Hose anyway...? Would you use it in the context of many people, like "Ihre Hosen" meaning "their (multiple pairs of) pants"? German is much more logical than English, and yet it's still so confusing.

Why is it not sein/seine
