Final answer:
The language of 'Beowulf' in Old English is archaic, with unheard words like 'theodcyninga' adding to the poem's mystic atmosphere. Repetition and alliteration create a rhythmic and musical quality.
Step-by-step explanation:
When listening to an excerpt from Beowulf, one may notice that the language of the poem is notably archaic, reflecting its Old English origins which date from 450 to 1066 A.D. Phrases like "Hwæt. We Gardena in geardagum, þæodcyninga, þrym gefrunon" showcase an ancient lexicon that is quite distinct from modern English.
Words such as 'þæodcyninga' (kings of people) and 'þrym' (glory) hold a mystic feel due to their historical context and unfamiliarity to contemporary audiences.
The poem's structure also contributes to its unique sound, with the use of alliteration and repetition as essential elements. For instance, the repetition of consonantal sounds at the beginning of words creates a rhythmic and musical quality when the poem is read aloud, engaging the listener and drawing them into the tale of legendary feats. This stylistic choice enhances the mythical atmosphere of the poem, depicting heroic deeds from a distant past.
