For now, I've decided not to use w and y (or j) for the semivowel versions of u and i, but just to use u and i, specifying that they become their semivowel equivalents when next to another vowel. That keeps two letters from going to waste. And I proposed keeping diphthongs from forming by putting a hyphen between the letters. But I could use the Loglan comma instead, as Steve Rice wrote:
If you want to break a diphthong into two separate sounds, put a comma without spaces around it between the vowels when writing them in text. The name 'Lois', for example, would be written Lo,is in Loglan (Without this comma the oi in Lois would be pronounced oy and the name would rhyme with 'Joyce'.).
So it would work the same way in Tceqli.
pai = PIE
pa,i = PAH-ee
kau = COW
ka,u = KAH-oo
I think I like that better than the hyphen.
So that keeps j from being used up that way, and permits it to represent /Z/.
And q can continue to represent /N/.
So with these "changes" (some are just reversions to earlier ideas of Tceqli or Loglan) we have:
PRONUNCIATION OF TCEQLI
|I||India||IN dee ah|
|J||Juliet||JEW lee ett|
|N||November||NOH vem ber|
|R||Romeo||ROW me oh|
|S||Sierra||see AIR ah|
|U||Uniform||YOU nee form|
Now — whatever shall we do with "w"?
