Based on the provided data, the name "Malchijah" (H4441I) is a Hebrew proper noun referring to a person. The transliteration "mal.kiy.yah" breaks down into three components: "malak," which is likely the root of the name, "ki," an adverb, and "yah," a name-element commonly found in Hebrew personal names. The definition of "Malchijah" is essentially an attributive name, with "malak" likely related to the concept of power, authority, or kingship, and "yah" being a common name-element, possibly indicating a divine origin or relation. Therefore, the name "Malchijah" can be literally translated as "My King from Yah" or "King by/From God." Given that this is a proper noun with only one occurrence in the Bible, its significance is context-dependent and likely limited to its role as a personal name within that specific narrative.
