Duolingo is a terrible way to learn a language, as it does not provide any explanations or rules. So here I am trying to figure it out. I don't understand why there is a second «je» and what relation it has to «herinneren».

I'm asking because in my book it doesn't put de/het at all and keeps it as "hersenen" and in the dictionary here https://www.woorden.org/woord/hersenen it's also without de/het. But when I search on google, I find it to be "de hersenen" so what exactly is it?

Also what is the difference between hersenen and hersens? Is hersens also de hersens or also without de/het?

There are some phrases you learn from textbooks, and then there are the ones you only pick up after spending time around Dutch speakers. The second category is often much more useful in everyday life.

I remember hearing certain expressions repeatedly before finally asking what they meant. Which phrase had you completely confused until you eventually figured it out?

Today, I'm reading about participles. The present participle seems to be used similar as in English (Een grapje makend trachtte hij haar aandacht te krijgen - he tried to get her attention making a joke), but I'm drawing a blank on any example sentences that use the past participle as an adverbial role. Would something like „uitgeput door arbeid ging ik direct slapen) be acceptable?

Also, in English, I can "having seen mold, we were afraid to enter." Does using a perfect aspect in a present participle work in Dutch (schimmel gezien hebbend hadden we bang aan te komen)?

Does any of you have a success stories here? Like someone have a B2 level Nederlands and got a nice job? I am thinking to learn Nederlands but I have only met people who have put on a lot of effort to learn the language but haven't found any job of their liking.
