Okinawan definitely has a particle equivalent to the Japanese subject particle が.
But I can't seem to find something like the topic particle は or the object particle を.
Then again I only have limited materials and they're in Japanese, which I can't really read very much of.
So I'm not sure whether this is a big difference between the languages, or there are such particles but I just can't find them.
Information on these particles in any of the other sister languages of Japanese is welcome.
(For the purposes of this question I'm only asking about these three particles that show the major grammatical roles of the nouns, I'm not asking about any of the other particles for now thanks.)
