ok, thanks. I wasn't aware of these examples, which answer as well the next thing I was wondering, with regards to if we should write {De' law'} or {De' vItlh} for "many information". I guess {De' vItlh} would be the preferable choice, since {vItlh} "is used for things that are measurable or quantifiable, but not necessarily countable".

Although, since we have the Ca'Non example of:

{chIch vay' 'oy'moHmeH 'oy'naQ 'ul law' tlhuD 'oH}
Painstiks ... emit a highly ­charged shock for the express purpose of
inflicting pain. S32

One could wonder what would be the actual difference in meaning (if any), between writing {De' law'} and {De' vItlh}.

True ! In fact, the reason I've wondered about all this in the first place, is because in greek the word "information" is countable, and it would sound wrong to say "we obtained valuable information (singular)".
