How does the poet use alliteration to describe grendal?

The poet uses alliteration, the repetition of initial consonant sounds, to emphasize Grendel's monstrous characteristics and highlight his destructive nature. By using alliteration, the poet creates a sense of rhythm and emphasis in describing Grendel's actions and attributes. One example is the description of Grendel as "hell's half-born brute" where the repetition of the 'h' sound adds to the feeling of hostility and aggression associated with Grendel. Another example is "his hands the horror-horned Grendel tore," where the repetition of the h sound creates a more forceful and graphic image of Grendel's attack. The use of alliteration in these descriptions builds upon the menacing aura surrounding Grendel and serves to enhance the tension and horror elements in the poem.
