Question

Which word in this excerpt from act I, scene I, of Richard III means “to listen”?

Answer 1

Yea, Richard, when I know; for I protest As yet I do not: but, as I can learn, He hearkens after prophecies and dreams; And from the cross-row plucks the letter G.And says a wizard told him that by G His issue disinherited should be; And, for my name of George begins with G, It follows in his thought that I am he. These, as I learn, and such like toys as theseHave moved his highness to commit me now.

the answer is hearkens 

Answer 2

Since you didn't provide the excerpt, I am going to assume that the answer you need is 'hearken'.
