Common Spelling and Grammatical Errors on the Internet

The following is simply a collection of the most obvious and common language errors I have noticed lately on the internet. Their appearance here indicates a consistent pattern and not just random typing errors ("typos") or unfamiliarity with the language (foreign and new speakers).

Type	Penetration	Incorrect Form	Correct Form	Explanation	Mnemonic*

Spelling	Common	definately	definitely		Finite or infinite, not finate or infinate
Spelling	Common	your (for "you are")	you're	Two words are run together: you are becomes you're
Spelling	Common	its (for "it is")	it's	Two words are run together: it is becomes it's
Spelling	Common	it's (that which belongs to it)	its		Same as most other possessive pronouns: his, hers, ours, theirs (exception: one's)
Spelling	Common	to (more than needed, or "also")	too		o+o
Spelling	Occasional	now (to have knowledge of)	know		You don't always know it now
Spelling	Occasional	seperate	separate		The 2 e's are separated by 2 a's: e-a-a-e
Spelling	Occasional	were (the location of something)	where		Note the pattern: Where? Here and there

Grammatical	Pandemic	There's ("there is") apples† somewhere	There are apples somewhere		Rearrange: Does "Apples is there" really sound right to you?
Grammatical	Common	... was the former ...	... is the former ...	Unless you are talking about a time prior to the present but after the time in the past when the condition existed, the state of being "former" exists now, not then.	This type of temporal grammar is about logic. Think about what existed when

Punctuation	Pandemic	Hyphen - used to replace a colon (:) or semicolon (;) in less than rigorously formal discourse	M-dash―named after its size in metal type	Hyphens (-) are used to break compound words and to run-on words at the ends of lines, not to break up sentences in the manner of colons and semicolons. If your HTML program doesn't have a list of symbols, the code for the M-dash (―) is —. If you don't have access to the underlying HTML, a double hyphen (--) may be used	Hyphens (-) are small; they break up small units like words. M-dashes (―) are large; they break up large units like clauses and sentences
