Final answer:
The nonsense word 'frabjous' in 'Jabberwocky' can be best replaced with the word 'joyful', based on the context of celebratory expressions surrounding it. Option number a is correct.
Step-by-step explanation:
The line “O frabjous day! Callooh! Callay!” from “Jabberwocky,” by Lewis Carroll expresses a sense of celebration and joy. The nonsense word “frabjous” can be replaced with joyful based on the context clues of this line.
Lewis Carroll's use of nonsense words, such as “frabjous,” creates a magical and shadowy mood despite the words' lack of definitive meanings. This technique allows readers to interpret the mood and atmosphere of the poem without strict reliance on traditional vocabulary, engaging their imagination and emotions.
