Lewis Carroll

Well, "slithy" means "lithe and slimy."  "Lithe" is the same as "active."  You see it's like a portmanteau - there are two meanings packed up into one word.

'Who's been repeating all that hard stuff to you?'
'I read it in a book,' said Alice.  'But I had some poetry repeated to me, much easier than that, by - Tweedledee, I think it was.'
'As to poetry, you know,' said Humpty Dumpty, stretching out one of his great hands, 'I can repeat poetry as well as other folk, if it comes to that - '
'Oh, it needn't come to that!' Alice hastily said, hoping to keep him from beginning.

'I took a corkscrew from the shelf:
I went to wake them up myself.

And when I found the door was locked,
I pulled and pushed and knocked.

And when I found the door was shut,
I tried to turn the handle, but - '

There was a long pause.
'Is that all?' Alice timidly asked.
'That's all,' said Humpty Dumpty.  Good-bye.'
This was rather sudden, Alice thought: but, after such a very strong hint that she ought to be going, she felt that it would hardly be civil to stay.  So she got up, and held out her hand.  'Good-bye, till we meet again!' she said as cheerfully as she could.
'I shouldn't know you again if we did meet... you're so exactly like other people.'

'I see nobody on the road,' said Alice.
'I only wish I had such eyes,' the King remarked in a fretful tone.  'To be able to see Nobody!  And at that distance, too!  Why, it's as much as I can do to see real people, by this light!'

A minute goes by so fearfully quick.  You might as well try to stop a Bandersnatch!

'He's dreaming now,' said Tweedledee:  'and what do you think he's dreaming about?'
Alice said 'Nobody can guess that.'
'Why, about you!' Tweedledee exclaimed, clapping his hands triumphantly.  'And if he left off dreaming about you, where do you suppose you'd be?'
'Where I am now, of course,' said Alice.
'Not you!' Tweedledee retorted contemptuously.  'You'd be nowhere.  Why, you're only a sort of thing in his dream!'
'If that there King was to wake,' added Tweedledum, 'you'd go out - bang! - just like a candle!'
'I shouldn't!' Alice exclaimed indignantly.  'Besides, if I'm only a sort of thing in his dream, what are you, I should like to know?'
'Ditto' said Tweedledum.
'Ditto, ditto' cried Tweedledee.
He shouted this so loud that Alice couldn't help saying, 'Hush!  You'll be waking him, I'm afraid, if you make so much noise.'
'Well, it no use your talking about waking him,' said Tweedledum, 'when you're only one of the things in his dream.  You know very well you're not real.'
'I am real!' said Alice and began to cry.
'You won't make yourself a bit realler by crying,' Tweedledee remarked:  'there's nothing to cry about.'
'If I wasn't real,' Alice said - half-laughing though her tears, it all seemed so ridiculous - 'I shouldn't be able to cry.'
'I hope you don't suppose those are real tears?'

'Can you keep from crying by considering things?' she asked.

'That's the way it's done,' the Queen said with great decision:  'nobody can do two things at once, you know.

'It's very provoking,' Humpty Dumpty said after a long silence, looking away from Alice as he spoke, 'to be called an egg - very!'
'I said you looked like an egg, Sir,' Alice gently explained.

'I beg your pardon?' Alice said with a puzzled air.
'I'm not offended,' said Humpty Dumpty.

'And how, who am I?  I will remember, if I can!  I'm determined to do it!'  But being determined didn't help much...
