According to Nicholas Milasith, from Kobold Press, the Sobriquet is a "fake name" that describe some action or event on the kobold's life, that is used to define who he is. This is not the real name of the kobold, but is a name that he is known for among others of his race, and the name that he gives to other races, as they probably can't pronounce his real name correctly anyway.
The too-talls shake their hairy heads at the bizarre array of names that kobolds call themselves. Kobolds see this as an opportunity to trick and confuse their rivals, of course. Most kobolds share only their sobriquet with other races and are not afraid to make up a new one on the fly if necessary. This does not help them with their own kind, who give honest, but sometimes cruel, sobriquets to their fellow kobolds. A sobriquet can define a kobold: Guttersneak is shifty, Goldscale is noble.
A kobold looking to redeem herself must literally make herself a new name: by actions, not words!
There is also a Kobold Name Generator provided by Kobold Press, with a .csv file containing a table with 100 different entries for each column, which is randomized by the application.
That table has surnames prefixed with (m) and (f) for males and females. So, whenever you feel like creating a new name, all you have to worry about is the surname (Suffix) being the correct gender, others can be randomized at will. The prefix (Root) can be randomized freely, and the same can be done for the two parts of their Sobriquet (these are gender neutral).
Given the two table entries you listed, you could end up with a male name as Ano or Iko, or a female name as Anta o Ikta, and any variation of sobriquets.
