(repeating from Gotchas)
See also naku.
This means "Not all of the brodas are brode". To say the more intuitive "(Each of) the broda(s) are not brode", the negation must be "na ku" and follow the le sumti, "le broda ku na ku brode".

That doesn't make any sense. And even if it did, it seems broken that that elidable terminator can affect the semantics like that.

As it turns out:
naku is a floating sumti, and not a 'tense', like normal na; so this isn't just a matter of an elidable terminator. In fact, in ro da naku su'o de na klama, the two na are doing quite different jobs; and the ku is not elidable there at all.
Of course, the 'user-friendly' way to approach this is to dodge na completely, and use na'e in this case.
This is only an issue if there is more than one of le broda. If there is exactly one, they both mean the same.
Also, le broda naku brode is equivalent to no le broda cu brode.
