Question

In this poem, seemingly "nonsense words" like "Jabberwock,"

"Bandersnatch," and "Tumtum" are capitalized. This indicates
that
A
B they are important.
C
they aren't really meaningful.
D
they are especially silly.
they are meant to be specific names of things

Answer 1

They are meant to be specific names of things

in English, in order to denote a proper noun (person, specific place, title, etc.), we capitalize the word. For example, Joe Biden is the current President of the United States of America. Notice how names, titles, and specific places all got capitalized.

If a capitalized word is not at the beginning of a sentence or in a title, it denotes a proper noun.

hope this helps
