Drû
From Tolkien Gateway
Drû (pl. Drúin, coll. Drúath) is the Sindarin name for the mysterious people of Men who became known as the Woses in the Third Age.
Usage of plural
- Drúin is the simple plural of the word.
- The collective Drúath was modified as early as the First Age when it became known that they were enemies of the orcs. Later used to refer to a large number of the Drúedain.
- Drúedain refers to the race as a whole.
Etymology
This Sindarin word comes from Drughu the Drúedain's own name for themselves.
Since Elvish don't have gh it was derived as drughu > dru'u > druu > drû
