The Adûnaic word for “pillar” (SD/241). Tolkien explained that this word is perceived as having a verbal function: “that which supports” (SD/429). As such, it can be used with an objective form in the name Minul-târik “That Which Supports the Heavens”.
Conceptual Development: In earlier drafts of “The Notion Club Papers” stories, this word appeared tûbal (SD/363), tūbil (SD/305) and (Quenya?) tyūlā (SD/346).
