Valamedar
Valamedar, in the fictional world of Middle-earth created by J.R.R. Tolkien, is a Quenya word meaning "Power-guardian" or "Ruler of Valinor". It is a compound word consisting of Vala (singular of Valar, the Powers of Arda) and melda (power, might), plus the agentive suffix -r, indicating the "one who" performs the action or possesses the quality. Thus, it designates an individual with authority and guardianship derived from the Valar.
The term is primarily used as an epithet or title, generally referring to a particularly significant figure or entity closely associated with the Valar and Valinor, the Undying Lands. The meaning emphasizes the individual's role as a protector and enforcer of the will of the Valar within their domain, or in connection with their purposes concerning Middle-earth. It implies a close relationship and delegated authority from the Valar themselves. While specific instances of usage are limited, the word carries significant weight due to its association with the highest beings in Tolkien's cosmology and the blessed realm of Valinor.
