By the way, thinking of another fixed expression, *tu'lu'*: I know Okrand compared it to English *there's* referring to plural, you were discussing that some weeks ago. But since I'm not an English native speaker, I don't know know how acceptable this use is in formal texts. Or in other words: when I write a formal text in Klingon, should I use *lutu'lu'* for a plural object, or is the form *tu'lu'* also acceptable?
It appears that tu'lu' is also a fixed expression. You can say things like Dujmey tu'lu' There are ships.
I don't remember Okrand comparing English there's referring to a plural noun. You wouldn't do this in formal English, and even in casual conversation saying something like there's ships in orbit might be noticed, though it's unlikely anyone but a stickler would comment on it.
I don't think Klingon tu'lu' in reference to a plural
noun can only be used informally. It is even used this way without
comment when we are introduced to it (naDev puqpu' tu'lu').
