The Klingon alphabetical order is as follows:

 

a, b, ch, D, e, gh, H, I, j, l, m, n, ng, o, p, q, Q, r, S, t, tlh, u, v, w, y, '

Note that ch, gh, ng, tlh and ' are considered letters in their own right, and that, as a result of this, the word nob would come before ngab in a Klingon alphabetic listing. q and Q represent two different sounds, and are thus sorted as two different letters.

tlh tlhay
To learn how to say this Klingon sound, first say l, then keep your tongue in the same position and exhale. Now repeat this, but let the air build up pressure behind your tongue before releasing it. The resulting sound should be voiceless, and you should be able to feel the air escape quite forcefully on both sides of your tongue.
u 'ut
As in gnu, prune or soon, never as in but or cute.
v vay
As in vulgar or demonstrative.
w way
As in worrywart or cow.
     
  • aw, rhyming with English "cow."
  • ew, not like anything in English. Basically the "e" in "bed" run into a "w." A good way to get to this is to think of Elmer Fudd saying "tewwible."
  • Iw, also unlike anything in English. Again, it's like the "i" in "bit" run into a "w." It's close to "Eww!" the expression of disgust.
y yay
As in yodel or joy.
     
  • ay, rhyming with English "why."
  • ey, rhyming with English "may" (Note: The Klingon word may, of course, sounds like English "my." See above).
  • Iy, rhyming with English "key."
  • oy, rhyming with English "boy."
  • uy, sort of like English "gooey," but not quite. It's one syllable, while "gooey" is two. Think of English "Do you" and drop off the last vowel sound.
' qaghwI'
As in the abrupt cut-off of sound in uh-oh or unh-unh meaning "no". At the end of a word this sound is usually followed by a soft echo of the preceding sound.
