Ent

Ents are giant humanoids in J. R. R. Tolkien's fantasy world of Middle-earth who closely resemble trees; their leader is Treebeard of Fangorn forest. Their name is derived from an Old English word for "giant".

The Ents appear in The Lord of the Rings as ancient shepherds of the forest and allies of the free peoples of Middle-earth during the War of the Ring. The Ent who figures most prominently in the book is Treebeard, who is called the oldest creature in Middle-earth. At that time, there are no young Ents (Entings) because the Entwives (female Ents) were lost. Akin to Ents are Huorns, whom Treebeard describes as a transitional form of trees which become animated or, conversely, as Ents who grow more "treelike" over time.
