What does Alice understand of the poem jabberwocky?

In the book "Through the Looking-Glass, and What Alice Found There" by Lewis Carroll, Alice does not understand the poem "Jabberwocky". The poem is presented as nonsense verse, filled with made-up words and unusual syntax, making it difficult for Alice to decipher its meaning. She struggles to interpret the words and actions described in the poem, and remarks that it seems to be "something about snakes" but acknowledges that it is "all mimsy".

Throughout the interaction between Alice and Humpty Dumpty, who explains the poem to her, Alice continues to express confusion and struggles to comprehend the explanations provided. Humpty Dumpty's interpretations are often nonsensical and arbitrary, further adding to Alice's bewilderment.

Ultimately, Alice's response to the poem "Jabberwocky" reflects the nature of the work itself as whimsical, nonsensical, and open to various interpretations.
