Nemo impediat? = May nobody hinder/entangle (your way)

According to Pia it should read:

"Don't let anyone stand..."

Isn't this the same for (metaphorical) meaning, if not literally? (If I stand in your way, I make it impossible or very difficult for you to do what you wanted to do.) If you don't agree, feel free to reject

Yes, dear. I also believe that a sens of "standing in a way" is the same with "hindering" here.
I just think that the key verb here is "to let", "to allow". In Latin we express it by "permittere".

O help, I think this is getting too complicated for my very basic Latin

Something like

neminem permitte impedire viam tuam

perhaps? But really, feel free to reject my attempt and translate it yourself; it will be faster and better, I'm sure!

Ooops! Sorry Lein. I have just noticed your post above. You were almost right this time.
I edited and started the poll.
