The words which describe the relationship between Hrothgar and Beowulf were mutual respect and loyalty.
Step-by-step explanation:
In spite of the fact that Beowulf and Hrothgar had no close to home relationship before Beowulf landed to kill Grendel, Hrothgar knew Beowulf's dad, regarded him and accepts that Beowulf may have the option to help spare Heorot. The storyteller in Beowulfdescribes Grendel as a beast who was thrown out from seeing men.
Accordingly, Beowulf feels some devotion toward Hrothgar. In spite of the fact that Hrothgar was a relentless warrior in his day, when the epic story in Beowulf happens he is an old lord, no longer ready to guard his kin against the pillaging devil Grendel. He'd presumably rather be playing shuffleboard now.
