Answer:
Beowulf is characterized as a hero by the semantic field.
Step-by-step explanation:
At the beginning of the excerpt, the object, Beowulf, is characterized as one that looks and is part of liege-kinsman, investing him in a very particular role, specially by mentioning Beowulf's father (Higelac). The adjectives and adverbs also contribute to this characterization ("stood up straight and stoutly did seize him".) The actions referred to the speaker are also impressive due to the sound of them (crackled and outward repeat strong consonant sounds such as "k" "r" or "t").
