Explanations of grammar
Does Duolingo include explanations of grammar anywhere? I've gone through a few lessons and found that I have to figure out things as I go, without any kind of general rules being provided. E.g., I did not see a rule that says that adjective gender has to agree with noun gender, or a rule about how to form past tense. Did I miss this somehow or does the site expect students to figure this out or memorize by rote? Thanks.
There are no grammar explanations yet. Some things are explained by community members in insights, but apart from that, yes, you have to manage this by yourself. There are many sites with grammar rules.
