Don't rely just on those squiggly little red lines to alert you to misspelled word in your document. Spell check isn't a mind reader, and it can't decipher between some common 'like' words. Recently, Kaboodle.com listed what they considered their top 10 errors that flew under the spell check radar:
Its versus It’s (and all other apostrophes):
Confusing “its” and “it’s” is the most common error in the English language. That one minuscule apostrophe (or lack thereof) drastically changes the meaning of the entire sentence. “It’s” is a contraction of “it is,” whereas “its” refers to possession. Also, watch out for “your” versus “you’re.”
Sales versus Sails
Can you imagine writing on your resume that you “increased sails by 20 percent”?! Unless you’re applying to a job for a sail boat manufacturer, this careless mistake will probably get your resume sailing right into the recycling bin.
Affect versus Effect
There is a lot of confusion around this one but here’s the rule: “Affect” is a verb and “effect” is a noun. It’s as simple as that.
Would Have NOT Would of
The subtlety in pronunciation leads to the rampant misuse of this phrase; however “would of” is never correct and may make you appear as if you are not well-read.
Through versus Threw
“He threw the ball through the window.” “Threw” is a verb and “through” is a preposition. And speaking of “through,” be careful to make sure you don’t actually mean “thorough” or vice versa. The slight variation in spelling will not be picked up by a computer, but writing “I am through” when you mean “I am thorough” is quite ironic, don’t you think?
Then versus Than
Six is more than five; after five then comes six. “Than” refers to a comparison, while “then” refers to a subsequent event.
Supposed To NOT Suppose To
“Suppose” is a verb, meaning to think or to ponder. The correct way to express a duty is to write, “I was supposed to…”
Wonder versus Wander
You can wander around while you wonder why “wander” and “wonder” have such different meanings, yet sound oh so similar.
Their versus There versus They’re
OK, once and for all: “Their” is possessive; “there” refers to distance; and “they’re” is a contraction of “they are.”
Farther versus Further
While both words refer to distance, grammarians distinguish “farther” as physical distance and “further” as metaphorical distance. You can dive further into a project, for instance, or you can dive farther into the ocean.
So next time you send out that important letter, check it over with your own eyes. Especially if it's a cover letter. Make sure it's not addressed to Dear Sir or "Madman", that it doesn't say you are experienced in many "faucets", list the fact that you have consistently "tanked" in the top 10 percent of employees or that you have a "collage" background. Yep, it happens.
Need me to look something over? Its amazing what a second pare of I's will cache that the first one's didn't.
