Lewis Carroll wrote Alice in Wonderland in Oxford, England.

Alice in Wonderland was said to have been written/partially written in The Ravensworth Arms, a pub situated In Lamesley, Tyne and Wear.
In llandudno Wales

When Alice first sees the Mock Turtle in Wonderland, he is sitting on a rock.

They had not gone far before they saw the Mock Turtle in the distance, sitting sad and lonely on a little ledge of rock, and, as they came nearer, Alice could hear him sighing as if his heart would break

Other than that, the author gives no indication as to the location of the scene, except that there is some implication that they might be near the sea shore, as that is where the Lobster Quadrille must be danced, and the Turtle and the Gryphon give a demonstration of it, and their conversation is full of references to the ocean and to various sea creatures.

The origins of the phrase 'grinning like a Cheshire cat' are unknown, but there are several theories.

According to Martin Gardner, in his Annotated Alice, the two leading theories are that a sign painter in Cheshire painted grinning lions on the sign boards of local inns and that Cheshire cheeses used to be molded in the shape of a grinning cat. It is not known whether either of these theories is correct.

The phrase first appears in print in the second edition of Francis Grose's Dictionary of the Vulgar Tongue, from 1778:

"Cheshire Cat He grins like a Cheshire cat; said of any one who shows his teeth and gums in laughing."

The term was popularised by Lewis Carroll's 1865 novel Alice's Adventures in Wonderland.

Jabberwocky uses a combination of made up nonsense words, ordinary English and old fashioned English.

The nonsense words are:

• Jabberwocky
• Brillig
• Slithy
• Toves
• Gyre
• Gimble
• Wabe
• Mimsy
• Borogoves
• Mome
• Raths
• Outgrabe
• Jabberwock
• Jubjub
• Frumious
• Bandersnatch
• Vorpal
• Manxome
• Tumtum
• Uffish
• Whiffling
• Tulgey
• Burbled
• Snicker-snack
• Galumphing
• Beamish
• Frabjous
• Callooh
• Callay
• Chortled

The old fashioned words Carroll used were to make the poem seem antiquated and are, twas, hast and thou.

When Alice meets the Cheshire Cat he gives her directions to the Hatter's house and the March Hare's house. Alice decides to visit the March Hare on the grounds that, as she's seen hatters before, meeting a march hare will be more interesting. She recognizes the hare's house as it resembles a hare.

`In THAT direction,' the Cat said, waving its right paw round, `lives a Hatter: and in THAT direction,' waving the other paw, `lives a March Hare. Visit either you like: they're both mad.'

....after a minute or two she walked on in the direction in which the March Hare was said to live. `I've seen hatters before,' she said to herself; `the March Hare will be much the most interesting, and perhaps as this is May it won't be raving mad--at least not so mad as it was in March.'

....She had not gone much farther before she came in sight of the house of the March Hare: she thought it must be the right house, because the chimneys were shaped like ears and the roof was thatched with fur.

It was all very well to say `Drink me,' but the wise little Alice was not going to do that in a hurry. `No, I'll look first,' she said, `and see whether it's marked "poison" or not'; for she had read several nice little histories about children who had got burnt, and eaten up by wild beasts and other unpleasant things, all because they would not remember the simple rules their friends had taught them: such as, that a red-hot poker will burn you if you hold it too long; and that if you cut your finger very deeply with a knife, it usually bleeds; and she had never forgotten that, if you drink much from a bottle marked `poison,' it is almost certain to disagree with you, sooner or later.

Alice's Adventures in Wonderland

Time, which is represented as though it were a real person, is angry with the Hatter and has fixed things so that it is always six o'clock and therefore always teatime.

Alice sighed wearily. `I think you might do something better with the time,' she said, `than waste it in asking riddles that have no answers.'

`If you knew Time as well as I do,' said the Hatter, `you wouldn't talk about wasting IT. It's HIM.'...

'Now, if you only kept on good terms with him, he'd do almost anything you liked with the clock. For instance, suppose it were nine o'clock in the morning, just time to begin lessons: you'd only have to whisper a hint to Time, and round goes the clock in a twinkling! Half-past one, time for dinner!'...

`We quarrelled last March--just before HE went mad, you know--' (pointing with his tea spoon at the March Hare,)...

`And ever since that,' the Hatter went on in a mournful tone, `he won't do a thing I ask! It's always six o'clock now.'

A bright idea came into Alice's head. `Is that the reason so many tea-things are put out here?' she asked.

`Yes, that's it,' said the Hatter with a sigh: `it's always tea-time, and we've no time to wash the things between whiles.'

The Cheshire Cat is niether good nor evil. There are no 'good guys' and 'bad guys' in Alice's Adventures in Wonderland - there are just 'guys'

One of the interesting things about the Alice books is that, even though it takes place is a fantasy world populated by extraordinary creatures, the 'poeple' Alice meets are far more like real people than those seen in the majority of fiction, in that they are not bad or good, they are just people (just like in real life.)

What Alice found through the looking glass was the Looking-Glass World.

The full title of Lewis Carroll's second Alice novel is Through the Looking-Glass and What Alice Found There. Once she has travelled through the looking glass, she discovers the Looking-glass World, a fantastical place, similar to Wonderland.
