The 12th ruler of Númenor, whose Quenya name was Tar-Ciryatan “Shipbuilder, Shipwright” (PM/151). The first element of his name is the objective form of balak “ship”. Therefore, the second element magân most likely means “wright, ✱builder”. This name appears only in a draft list of the kings of Númenor from the early 1950s, and falls between the conceptual periods of Middle Adûnaic and Late Adûnaic in the terminology used here.

masculine name. Shipwright, *Shipbuilder
The noun for “ship”, attested only in the plural (balîk) and objective (balku) forms (SD/247, PM/151). Its plural form indicates that it is a strong-noun (Strong I), so its final vowel must be short. In theory its final vowel could be any of a, i or u, each of which would be replaced by long î in plural nouns. However, its attested objective form uses the variant objective-with-syncope form balku instead of ordinary ✱baluk. Since the Adûnaic syncope seems only to occur for nouns with two identical short vowels, this indicates the singular form of this word is balak.
