all right vs alright     

All right has multiple meanings. It can mean ok, acceptable, unhurt.

The single word spelling alright has never been accepted as standard.

Kingsley Amis The King's English 1997: "I still feel that to inscribe alright is gross, crass, coarse and to be avoided, and I now say so. Its interdiction is as pure an example as possible of a rule without a reason, and in my case may well show nothing but how tenacious a hold early training can take."

Bill Bryson Troublesome Words 1997: "A good case could be made for shortening all right to alright. ... English, however, is a fickle tongue and alright continues to be looked on as illiterate and unacceptable and consequently it ought never to appear in serious writing."

Robert Burchfield The New Fowler's Modern English Usage 1997: "Alright ... is the demotic form. It is preferred, to judge from the evidence I have assembled, by popular sources like the British magazines The Face ... New Musical Express and Sounds, the American magazine Black World, the Australian journal Southerly, the Socialist Worker, by popular singers ... and hardly ever by writers of standing ... It is commonplace in private correspondence, especially in that of the moderately educated young. Almost all other printed works in Britain and abroad use the more traditional form ... "
(At which point in there did you first get the urge to smack him?)

Graham King The Times Writer's Guide 2001: If we accept already, altogether and almost, why not alright? Although it carries with it the whiff of grammatical illegitimacy it is and has been in common use for a century ..."
  
alone / lonely     

Alone, can be used as an adjective or adverb. Either use means without other people or on your own.

For example: "He likes living alone."
"I think we're alone now." = There are just the two of us here.

Lonely is an adjective which means you are unhappy because you are not with other people.

For example: "The house feels lonely now that all the children have left home."

!Note - Just because you're alone, doesn't mean you're lonely.
  
a lot / alot / allot   

A lot, meaning a large amount or number of people or things, can be used to modify a noun.

For example:-

"I need a lot of time to develop this web site."

It can also be used as an adverb, meaning very much or very often.

For example:-

"I look a lot like my sister."

It has become a common term in speech; and is increasingly used in writing.

Alot does not exist! There is no such word in the English language. If you write it this way - imagine me shouting at you - "No Such Word!"

Allot is a verb, which means to give (especially a share of something) for a particular purpose:-

For example: "We were allotted a desk each."
  
all ready vs already   

All ready means "completely ready".

For example: "Are you all ready for the test?"

Alreadyis an adverb that means before the present time or earlier than the time expected.

For example: "I asked him to come to the cinema but he'd already seen the film."
Or
"Are you buying Christmas cards already? It's only September!"
  
altogether vs
all together     

All together (adv) means "together in a single group."

For example: The waiter asked if we were all together.

Altogether (adv) means "completely" or "in total ".

For example: She wrote less and less often, and eventually she stopped altogether.

!To be in the altogether is an old-fashioned term for being naked!
  
any one vs anyone     

Any one means any single person or thing out of a group of people or things.

For example:-

I can recommend any one of the books on this site.

Anyone means any person. It's always written as one word.

For example:-

Did anyone see that UFO?
  
any vs some     

Any and some are both determiners. They are used to talk about indefinite quantities or numbers, when the exact quantity or number is not important. As a general rule we use some for positive statements, and any for questions and negative statements,

For example:-

I asked the barman if he could get me some sparkling water. I said, "Excuse me, have you got any sparkling water?" Unfortunately they didn't have any.

!Note - You will sometimes see some in questions and any in positive statements. When making an offer, or a request, in order to encourage the person we are speaking to to say "Yes", you can use some in a question:

For example: Would you mind fetching some gummy bears while you're at the shops?

You can also use any in a positive statement if it comes after a word whose meaning is negative or limiting:

For example:-
A. She gave me some bad advice.
B. Really? She rarely gives any bad advice
