What is Treebeard’s name for a gathering of the Ents? Treebeard calls such a gathering an Entmoot, also written as “Ent Moot.” In J. R. R. Tolkien’s Middle-earth, the Entmoot is a formal assembly of the tree-like Ents.

In The Lord of the Rings, Treebeard brings Merry and Pippin to an Entmoot in Fangorn Forest. The Ents gather to discuss Saruman’s destruction of the forest and decide what action to take. Their deliberations are famously slow because Ents are ancient beings who consider words and decisions very carefully.

The meeting lasts three days. It eventually leads to the Ents’ march on Isengard, Saruman’s fortress. The Ents destroy much of the stronghold and flood its industrial works by diverting the River Isen. This becomes one of the decisive actions of the War of the Ring.

“Entmoot” is the canonical one-word spelling commonly used in Tolkien references, while “Ent Moot” conveys the same meaning and is a fair answer. It should not be confused with “moot” in the modern sense of a merely debatable question.
