If one doesn’t know the intention then how can ones intent be sound or even existing? If you don’t provide a translation, then you may as well be writing “your mama is a fat jerk who can’t cook well” in some other language. For this very reason, 100% of the incantations that people write on here in their fancy rituals are not ever going to be spoken by me because I don’t know what their incantation actually means. Therefore, doing incantations in this manner is really a waste of a good ritual unless you have people who are completely fine trusting strangers (I’m not) and just doing blind incantations.
If you don’t have any meaning to attach intent to, then I have to disagree with the popular belief that just intent is enough. You have to know what you are intending with said incantation. Even with an enn, we know that the intention is to call them to us (come here, you), in a fancy way.
