The question was raised on Auxlang whether the Esperanto J-plural used for both adjectives and nouns is the same independent phoneme. Here's an example which I throw out for consideration. Recently I showed my two-year-old son that if you take two mirrors such as what we have in our bathroom cabinet, and position them in a certain way with your head inbetween them, you see about 6 reflections of your head. My son really likes this. He calls it "tri Gxonaj". I don't think we ever said anything like that to him before. So, assuming that he made this up himself, a child that can't really count to 6 can figure out that: - J is a plural ending. - when applied to nouns that end in "a", it's pronounced "aj" (and not 'o' 'on' 'oj' or 'ojn') I suppose an alternate explanation is that he thinks his name is an ajective, and that he's a "Gxona" (jonish?) person -- so "tri gxonaj" means "three Jonish ones." I find the first explanation easier to believe. Thomas - Rochester NY USA
