[akhtene]

Ents - a people (race ??) created by Yavanna, tree-herds and guardians of ovlar. They have their own language (Entish) but can speak Quenya and other languages as well.

Fangorn tells hobbits about trees which were awakened by elves, taught their language,and became kind of entish. Some of them are quite evil ('have bad hearts'). I think the Old Man Willow is an example of such a tree.
Perhaps entish trees = huorns (I'm not sure) .
