I would change "ku" to "cu". "cu" seems to be a lot more common, and I think it sounds more natural.

As explained in L4B (I think), the beginning of a "verb" is generally more important than the end of a "noun".

I'm very solidly in the "don't use {cu} unless you have to" group. And it sounds perfectly natural to me. Feel free to add another sentence with the replacement.

And thank you for the comment.

Just curious, but what is your reasoning for that?

Would you say "lo nu broda lo brode kei ku brodi" instead of "lo nu broda lo brode cu brodi"?

It really depends what mood I'm in, for that. Probably when faced with multiple elide-able terminators I would use {cu}. But in the case of a single terminator, I prefer to use it. So I would say {lo mlatu ku melbi} but I would also say {lo nu pinxe lo djacu cu xamgu}. Part of it may be that I was never comfortable with {cu}. It took me a long time to actually understand what it did, and I still can't use it properly 100% of the time. So I tend to avoid it.

Hmm, that's interesting. I've heard that some people have had a hard time understanding "cu", but I never really understood that.

I started learning Lojban with Lojban for Beginners, which uses "cu" throughout. I remember that after seeing some example sentences, "cu" made perfect sense to me. This was my explanation:

Whenever a sumti precedes a selbri, "cu" takes the place of any terminators for the outermost sumti that is "complete".

So "lo nu lo nu broda cu brode cu brodi" is "lo nu lo nu broda kei ku brode kei ku brodi".

If a sumti is not "complete", then "cu" goes farther in. So "lo nu lo broda cu brode cu brodi" is "lo nu lo broda ku brode kei ku brodi".

Obviously, this is somewhat complicated, but I don't think it's hard to remember. It seemed pretty natural to me and I don't think I've ever messed it up (except for making obvious mistakes like "lo broda brode" instead of "lo broda cu brode", but that is just as easy to do with terminators).

How did you learn Lojban? I wonder if it's just a matter of what one hears first. Someone who uses L4B might be inclined to use "cu" and someone using the Wave lessons might be inclined to use "ku". I remember that xorlo seemed weird to me for awhile since L4B uses "le" mostly.

Huh, interesting.
Well, I learned Lojban starting with the CLL (I know, wonderful, right?) Then I tried L4B and only got the very basics out of it before it stopped making sense to me for some reason (perhaps because of {cu}, which simply made no sense to me), and then I contacted Lindar and he taught me over Skype, which is when I /really/ started to get things down. Now I learn mostly through asking questions on IRC.
I guess {cu} just overcomplicated things for me. I didn't see what it could be used for that you couldn't do with terminators. Now I can use it when I need to, but I'm still not great with it, as I said, because for some reason it doesn't quite click with me.
