§ Of the Coming of Men into the West The Silmarillion

Now the Eldar were beyond all other peoples skilled in tongues; and Felagund discovered also that he could read in the minds of Men such thoughts as they wished to reveal in speech, so that their words were easily interpreted. It is said also that these Men had long had dealings with the Dark Elves east of the mountains, and from them had learned much of their speech; and since all the languages of the Quendi were of one origin, the language of Bëor and his folk resembled the Elven-tongue in many words and devices. It was not long therefore before Felagund could hold converse with Bëor; and while he dwelt with him they spoke much together. But when he questioned him concerning the arising of Men and their journeys, Bëor would say little; and indeed he knew little, for the fathers of his people had told few tales of their past and a silence had fallen upon their memory. 'A darkness lies behind us,' Bëor said; 'and we have turned our backs upon it, and we do not desire to return thither even in thought. Westwards our hearts have been turned, and we believe that there we shall find Light.'
