Please analyze the diction in "Jabberwocky" to make it more understandable to a modern reader.

The “tale” of this short, ballad-like poem is that an
unnamed hero goes forth, defeats the monstrous Jabberwock and returns victorious. The
diction can very well be understood by the reader, especially one asks to
prepare some thoughts about an ancient tale beforehand. When you think about the poem,
one might think to consider how one can tell what part of speech (noun, verb, adjective)
a specific word is supposed to be. The answer, of course, is that Carroll’s syntax
defines the role of each  made-up word absolutely. Here are some of the more obvious
contemporary words you might decipher: slithy = slippery + slithering + lively + lithe;
toves = toads + doves; gimble = gambol + nimble; manxome = maximum + noxious + fearsome;
galumphing = galloping + lumbering + lump; chortle = chuckle + snort (“Chortle” has
become a popular word.)
