[lojban-beginners] lo brivla valsi

[Michael van der Gulik <mikevdg@gulik.co.nz>]

Hi all.

I want to say "Brivla are words". Now, how would you say that?

I could say:

lo brivla cu valsi
(some of those which really are brivla are words).

or

lei brivla cu valsi
(the mass of those I describe as "brivla" are words).

or I could say:

lo brivla cu cmima lo'i valsi
(one/some brivla are members of the set of words).

or even:

ro da zo'u da brivla .ijanai da valsi (if its a brivla, then its a word)

Another way of saying it would be
"The class 'brivla' are a subclass of class 'word'" (as in 
Object-Oriented terminology) but I don't know how to say that in lojban yet.

Which is the best way of saying this? And are the above sentences correct?

Mikevdg.
