Woses

A name among the Rohirrim for the shy, secretive people known in Elvish as the Drúedain. Though never populous, the end of the Third Age saw these people reduced to a few populations in the southern parts of Middle-earth, especially in the Drúwaith Iaur and Drúadan Forest of Rohan, where the Rohirrim came into contact with them.

In fact, the word 'wose' is a name from British folklore, referring to a hairy, troll-like being supposed to inhabit woods and forests. It represents Tolkien's translation of an actual word of the Rohirrim into ancient English; the Rohirrim themselves would not have called such a creature a 'wose', but a róg.
