Some info about Khajiit names: http://www.imperial-library.info/content/interviews-3-booksellers
Khajiti names have patterns of meaning.
"Jo" in Jobasha's name means "wizard." But Jobasha is no wizard, just a humble bookseller.
"Dar" in a Khajiti name means "thief," but this should not alarm you. "Dar" is like the Nordic "Clever Hudvar" or the Breton "Arnand the Fox." A Khajiit with "Dar" in his name is clever, and maybe clever with his hands, but not always a thief by your odd Imperial property customs.
"Do" in a Khajiti name means warrior. "Do" is rarely used by modern Khajiit, except for the Mane's guards. And masters of Goutfang, Whispering Claw, and Rawlith Khaj, of course.
Khajiti men show their status in life with their names, unless they choose a nickname. In Jobasha's case, as a "scholar," Jobasha uses "Jo" alone, not "S'basha-Jo," for using two titles shows great ignorance or great pride.
"M" or "Ma" means "child" or "apprentice" or, in the vernacular, "virgin." As an apprentice can be of any age, this leads to misunderstandings and jokes Jobasha cannot translate.
"J," Ji," or "Ja" means a bachelor or young advlt. In the vernacular, it means one who is young and lacks experience.
"S" is the most common, and means simply an advlt.
"Ra" and "Ri" show high status. "Ri" is the highest status among the Khajiit, used by leaders of cities or tribes.
"Dro" means "grandfather" and shows respect.
