Guys, it has to be one syllable, and then it has -Un on as the second syllable, then your titles, which would be -Sha for now, probably -Ga later (Hero).
So if we figure Ulla's full round of Titles to be Ulla-shamam it would break down like this.
Ull = Her true name, gender neutral. This is the only part she really chose.
-a = A "title" that says she's a girl. Meaning she's an egglayer (not anymore).
the hyphen = Represents a tiny pause separating them into two words. Could also be represented with a space but hyphen looks better.
-Sha = She's a shaman, a storyteller. Not a -Khet, a warrior, or a -Ka, a Chief.
-Mam = Pronounced like "Mom", meaning mother or Matron. Translates as a title into a female version of -Ka, though -Ka is gender neutral and implies chiefdom, so this is the most commonly used. A -Mam is usually not someone you want to mess with. Also, the -Mam title implies she's laid a fertilized clutch before, so someone in the tribe (or several, goblin clutches can be 10-20 eggs on the larger side) is likely carrying Ulla's genes. Goblins don't much care about that though, apprentices carry a parallel to children here.
This translates her name as "Ull, female, Mother of the Shamans." If she had any more, they would probably be superceded. Only the two most important can be tacked onto a name, though if you want to recite the whole list you can repeat the "Ulla" and tack on the others. Titles can be dropped with impunity, however, though it shows less respect the more and the more important the title dropped. Dropping the -Mam isn't so important, so it's acceptable, though if you wanted to go full-on respectful it's part of her title. Dropping the -Sha basically means you know her personally, like a friend. The -A can't really be dropped. That would go beyond disrespectful into just weird. They'd be offended, but in a tilted-head-and-spocked-eyebrow sort of way.
Roomba and Arkai are two syllables. You could be Roomun or Arkun, or Baun or Aiun. Rhomun would work. A little long to write but as this is second-person I doubt that would be too much of an issue.
