The word she uses, "alurlssrin", is specifically a word used by the faithful of Eilistraee, as an expression of their faith. Eilistraee is a drow goddess who is opposed to Lolth, and who leads her faithful to live on the surface in the light, in harmony with other races, which goes against Lolth's teachings.
It's very strange for Minthara, a Lolthsworn drow, to use a word like this, right? Eilistraee goes against everything she ought to stand for. My friend pointed this out in disappointment, as to her it's another example of Minthara's character writing having a lot less care put into it.
