  ====Nouns====
  There are four grammatical numbers in High Valyrian—singular, plural, paucal and collective. For example, ''vala'' "man" (nom. sing.); ''vali'' "men" (nom. pl.); ''valun'' "some men" (nom. pau.); ''valar'' "all men" (nom. coll.). The collective can itself be modified by number as a new noun declension, for example ''azantys'' "knight, soldier" (nom. sing.) → ''azantyr'' "army" (nom. coll.); ''azantyr'' "army" (nom. sing.) → ''azantyri'' "armies" (nom. pl.).
  Nouns have eight cases—nominative, accusative, genitive, dative, locative, instrumental, comitative and vocative, though the instrumental and comitative are not distinguished in all declensions, nor are the genitive, dative and locative always distinguished in the plural. Both prepositions and postpositions are used to form other cases; for example, the ablative is formed with the preposition ''hen'' + the locative (e.g. ''hen lentot'', "from a house") while the superessive is formed with the postposition ''bē'' following the genitive (e.g. ''lento bē'', "on top of a house").
  There are four grammatical genders, which do not align with biological sex. The Valyrian names for the genders are:
  : ''hūrenkon qogror''—"lunar class",
  : ''vēzenkon qogror''—"solar class",
  : ''tegōñor qogror''—"terrestrial class",
  : ''embōñor qogror''—"aquatic class".
  Animate and individuatable nouns are generally in the lunar or solar classes, while other nouns are generally classified as terrestrial or aquatic. The names of the classes derive from the nouns themselves, which are prototypical members of each gender. Peterson describes Valyrian gender as being inherent but more predictable from phonology than gender in French, with some of the derivational properties of the noun classes of Bantu languages. As a result of the phonological predictability, many words for humans (which tend to end ''-a'' or ''-ys'') are lunar or solar; many foods and plants (often ending ''-on'') are terrestrial.
  According to Peterson, "what defines declension classes in High Valyrian" can be divined by paying "close attention to the singular and plural numbers" and noting "where cases are conflated and where they aren't". In the following tables, adjacent case conflations are merged into the same table cell; other cases that share a form with another are underlined.
