[Nazgûl-king]

I have re-read this chapter recently and came across something interesting; when the eagles come to rescue Beren and Luthien from Angband’s gate it says

“Among all birds and beasts the wandering and need of Beren had been noised, and Huan himself had bidden all things watch, that they might bring him aid”

Now we are told that Huan could only speak three times, and none of those three times are talking to the animals, so how does Huan bid the animals to watch so that they can help Beren if he did not speak to them?
