Dovahzul for "my"

Hello! I really appreciate this site. Thanks for creating it!

My question is about the translation for the pronoun "my". The dictionary and the translator both have it as a separate word, "dii." However, the linked reference http://www.uesp.net/wiki/Lore:Dragon_Language says, "The singular possessive ("my", "your", "his", or "her") is formed by adding the letter "i" to the end of the word..."

So, if I wanted to say "My Thu'um," would that be "Dii Thu'um" or "Thu'umi"?
