From the notes in the first skill: "High Valyrian doesn't use a word like "and" when coordinating two nouns or two adjectives. Instead, the last word in a pair trio of nouns, adjectives, or even verbs is modified in some way to indicate that it is participating in a coordinative structure. One common strategy is to lengthen the final vowel of the last word in a list and shift the word's stress to the end."
