Parece improvável que existam outras palavras não oficiais quando você considera que George criou mais de 400 Casas. Além disso, ele nem inventou todas as palavras para aquelas. Existem algumas casas grandes como a Casa Frey que ainda não têm palavras.
Could you tell us some of the family words for those families we haven't seen yet, for example the words of House Frey?
I'd have to see whether I've created those words, I can't remember off-hand. I've a mountain of notecards at my home where I put down all this information. You have to realize I've made up more than 400 houses, and I haven't created words for all o them yet. I make them when I need them. Where's Elio when I need him?

Com isso dito, George sugeriu usar "Sapphires" como um substituto para as palavras de House Tarth em uma assinatura de livro, pois ele ainda não havia encontrado as palavras.
When it was my husband's turn to get our books signed, he told him he wanted the Stark words in two books, and the Tarth words (whatever they were) in the third. George said that he hadn't ever come up with words for the Tarths (maybe he will, now!) He laughed and said if we really wanted something about Tarth, he could just write "sapphires" - naturally, my hubby said, "no, sapphireth!" But ultimately he just put "Winter is Coming" in all of them.

Esta é apenas uma substituição fora do universo e não em palavras não oficiais do universo. No entanto, safiras são usadas por Jaime para manter ele e Brienne a salvo pelos homens de Vargo Hoat, embora Tarth não seja chamada de Ilha de Safira por pedras preciosas.
"Is every word you say a lie, Kingslayer? Tarth is called the Sapphire Isle for the blue of its waters."

Claro que isso ajuda a salvá-los de inúmeras datas desagradáveis enquanto estão no acampamento. A seguinte passagem também descreve de alguma maneira a referência do marido da pessoa na assinatura.
Cursing, Rorge kicked at his stump again. Jaime howled. I never knew there was such agony in the world, was the last thing he remembered thinking. It was hard to say how long he was gone, but when the pain spit him out, Urswyck was there, and Vargo Hoat himself. "Thee'th not to be touched," the goat screamed, spraying spittle all over Zollo. "Thee hath to be a maid, you foolth! Thee'th worth a bag of thapphireth!" And from then on, every night Hoat put guards on them, to protect them from his own.
