Oh and if it’s not too much work, could you perphaps elaborate on these functions for に:
- Marks indirect object (benificiary of verb being done)
- Marks the purpose for doing a movement verb
- Marks location-of-existence

Rereading it now I don’t think I quite understood what those meant exactly, so an example might help (but if TextFugu covers this in later chapters you can just ignore this.)

I don’t know what else to say other than thank you guys! I’ll actually go and rewrite my notes on both を and に now since your examples really helped to get to the bottom of the issue. I actually have not officially learned about へ or the other uses of に yet, so now I’ve gained some extra knowledge in advance, which will surely come in handy ;)
And thanks for the link Brook, I’ll make sure to check it whenever I come across a new particle!
