Recently, on the "learn klingon" facebook group, there was a discussion, with regards, whether the two nouns of a noun-noun construction can have adjectives.

For example {la' Dun vIghro' tIQ} "the ancient cat of the great commander".

Personally, I would avoid using such constructions, because they could be confusing.

However, I would like to ask, whether there is a rule prohibiting such constructions.

Because, although I've read that facebook thread, I still don't understand whether they're illegal or not.
