Hi, thank you very much for your reply! It's a bit tricky to explain - but here goes :-)
It's for a children's story, and the commander of a wwii tank shouts to the loader in the tank, that he should load the cannon with ammo. The tricky bit is, that I need the word "Lasse" (name in Danish) to be part of the command given. That's why I had hopes for 'Lasse die kanone', because "lasse" could mean both "load" and also be his name. But I guess it doesn't work.
I don't know if it makes sense to you at all. But perhaps you can come up with a different example where "lasse" (as a german verb) is included in the command, load the cannon?
