'Manxome' is a word invented by Lewis Carroll which he used to describe the monstrous Jabberwock in his poem Jabberwocky,but it is one for which he never gave a definition.
He took his vorpal sword in hand:
Long time the manxome foe he sought --
So rested he by the Tumtum tree,
And stood awhile in thought.
As such, we as readers have to define the word and choose a meaning for ourselves.
According to Dr Bill Long, the word is a portmanteau of the words 'manly' and 'buxom' and means 'fearsome' (See related link)
However, there is no evidence that this was Carroll's intention when he invented the word and as it does not follow the usual rules of portmanteau, this seems unlikely to be accurate.
In other portmanteau words, the new word carries the combined meaning of the words of which it is composed, for example 'mimsy' means 'miserable' and 'flimsy' and those are the words which comprise it. But, as the old uses of the word 'buxom' were 'vivacious' and 'compliant', it does not seem possible that when combined with the word 'manly' this would create the meaning 'fearsome'.
It is more likely that 'manxome' is not a portmanteau of 'manly' and 'buxom' at all and is one of the words in Jabberwockywhich lacks a definitive meaning.
In Lewis Carroll's poem "Jabberwocky," the word "manxome" is a nonce word, meaning it was created for a specific occasion and does not have a standard definition. It is often interpreted to mean something fearsome or ferocious, as it describes the Jabberwock, a creature that the protagonist must confront. The playful and imaginative language of the poem allows for various interpretations, but "manxome" contributes to the overall tone of danger and adventure.
"Manxome" is not a standard English word or recognized part of speech. It appears to be a nonce word coined by Lewis Carroll in his poem "Jabberwocky" to evoke a sense of unfamiliarity or otherworldliness. In linguistic terms, it could be classified as a lexical innovation or a blend of "man" and "fearsome" to create a unique adjective.
The only reference that I can find for 'manxome' is in the poem 'Jaberwocky' by Lewis Carroll. A word that is likely made up by Carroll. Some believe that it refers to 'fearsome Manx people, people of the Isle of Man. In the poem, the word manxome is used as a noun. "He took his vorpal sword in hand: Long time the manxome foe he sought-"
A word created by Lewis Carroll in "Jabberwocky" (Through the Looking Glass, 1872), it has no precise definition. Some suggest it means "fearsome" as in "manx-like".
"Manxome" is pronounced as "man-zuhm."
"Manxome" is a word invented by Lewis Carroll meaning "fearsome" and would therefore be an adjective.
In "Jabberwocky," the word "uffish" is used to describe the demeanor or expression of the character. It suggests a sense of irritability, impatience, or grumpiness.

"Hast" in the poem "Jabberwocky" means to have or possess something. It is an old English word that is used to indicate possession or ownership, similar to "has."
The tree mentioned in Lewis Carroll's poem "Jabberwocky" is the "vorpal blade" tree, from which the protagonist takes a sword to slay the fearsome Jabberwock creature. The vorpal blade is a weapon used by the hero to defeat the creature in the fantastical world of the poem.
A bird with feathers sticking out. It is a scruffy thin bird.
You could, but it depends what you mean. If you mean the person is a horrible beast, then you might want to say "Jabberwock" instead. The poem itself is called "Jabberwocky," so you would only be calling someone a poem.
