Halflings
From Tolkien Gateway
Halflings was a name for Hobbits used by Men; it was originally given to them by the tall Dúnedain. Though the Dúnedain had diminished in stature since the line of kings failed, at their greatest the had stood two rangar tall, making the average Hobbit about half their height. The name was still used by Gondorians in the Third Age.
The name "Halfling" is a translation from the Westron banakil which means "half-man". It was translated into both Sindarin and Quenya as Perian.
