1. When do I use M'ath, and when do I use M'ach, or does it matter?
They can be used interchangeably, speaker's preference. they are both contractions of
m'athchomaroon2. What do you do when you have a double consonant or a double vowel like in the word, 'Anna' (Me)?
Basically, you lengthen the sound, pronouncing each letter a little if possible, especially in the case of vowels. You can learn a lot more here (with pronunciation examples:
http://www.dothraki.com/2011/09/long-or-doubled-consonants/3. How do you pronounce the letters q, and r, in Dothraki?
The /q/ is basically an Arabic q. It's kind of fun to pronounce. Here is another of David's blog posts concerning this letter (with exercises):
http://www.dothraki.com/2011/11/qute-noises//r/ is fairly simple, especially if you can roll your r's. If the r occurs at the beginning of a word before a vowel (example
reaven 'purple color'), at the end of a word, or is doubled, it is trilled. Most Dothraki speakers do not trill r's particularly heavily, but I tend to.
In all other instances of /r/, you pronounce the r with a medial tap, essentially, a 'flipped' r. This is an r with a little bit of d or t sound associated with it.
--Help would be appreciated!!
Hope this helps. It's great to see someone here asking questions!
