Our reading
An editorial interpretation.
The sentence introduces an unfamiliar kind of inhabitant through the plain language of a dwelling place. Its matter-of-fact tone makes a hole in the ground sound like a perfectly ordinary home. The unexplained word 'hobbit' leaves space for curiosity about the life inside.
