Bad Grammar: i really shouda studied harder for my biology test

Good Grammar: I really should have studied harder for my biology test.

The bad grammar example was bad because it used the slang term “shoulda” it also did not start with a capital or end with a period.

Bad Grammar: Git ‘er done!
This is bad grammer because “get” is spelled wrong, and what does ‘er mean anyway?

So I found this example of bad grammar on a website, adapted it a bit to make it even worse, but am thinking with well explained corrections it should still qualify for our assignment, let me know if it doesn’t please.
Bad Grammar Example: if you love someone set them free
So there are quite a few things wrong with this group of words (it’s not really a sentence yet). First is that there is no punctuation or capitalization anywhere in the sentence. Every sentence must at minimum begin with a capital letter and end with a period. As this sentence also has a cause and effect type relationship between the first and second parts it needs a comma. The comma lets the reader know that the ending of the sentence is dependent on the beginning to make since and the beginning is incomplete without the ending. The final thing I noticed wrong with this sentence is that “someone” is a singular word and “them” is a plural word. In order to make the sentence more correct “someone” either needs to be changed to “them” or another plural type word or “them” needs to be changed to “him” or “her” (basically a singular word). So the
Corrected Sentence should Read: If you love someone, set her(or him) free.

George said, “George is getting upset.”
-George referred to himself in third person. He should of said, “I’m getting upset.”

I was in a car reck. The word reck actually means to have concern. The correct spelling of the word in this sentence is wreck which means the ruin or destruction of anything.

Its really bad weather outside today.

Improper use of the word its. “It’s” is the contraction for “It is” while the word “its” is used a possessive tense, as in “That bear you found, its mine.”

Where are you at?

That is bad grammar because you shouldn’t end a sentence with a preposition, as well as the fact that “at” is not necessary for the sentence to make sense.

I have a hard time with the differences between “affect” and “effect”. and words that are like that. examples:

1. The drug did not affect the disease.
In this case “Affect” is usually a verb meaning “to influence

2. The drug has many adverse side effects.
In this case “Effect” is usually a noun meaning “result”.

Bad grammar: Me and Jerry went to the star trek convention as Cpt. Kirk and Spock.
Good grammar: Jerry and I wish we had a better social life.

I used this example because I have problems with it in my normal speech.

Bad: I went to the park the baseball game and then to the party.
Good: I went to the park, baseball game, and then to the party.
The first example represents bad grammar because it is a list of three or more, and therefore needs commas after each item (as seen in the second example).

Bad: I’d much rather be sleeping then be in class.
Good. I’d much rather be sleeping than being in class.

“Then” is used when one dealing with time of some sort or sequences, where as “than” is used to compare things. A good tip I read on a grammar website is to practice actually pronouncing the words differently until they become different in your head and regular speech. At that point you can usually separate out the words enough in your mind to make it easy to use in writing.

I like learning about spaghettification in astronomy.
There is actually nothing wrong with that one. I just thought that was a funny word, it is a real word, but the spell checker on the blog marks it as wrong.

There is much to be happy about in this life; sometimes I eat peanut butter and jelly sandwiches.
It is wrong because using the semicolon here is linking unrelated clauses. The correct use of the semicolon links related clauses.

Bad Example: While searching for a good place to get a unicorn burger, i traveled to Seattle, Washington, London, England, and Provo, Utah.
Good Example: While searching for a good place to get a unicorn burger, I traveled to Seattle, Washington; London, England; and Provo, Utah.
The first example is bad because the over use of commas makes the sentence confusing and hard to read. Using a semicolon to separate the comma groups makes it understandable. I’ve experienced this when listing dates.

Bad Example: We run a set up program to setup a process.
The uses of both set up and setup are both wrong here. They should be the other way around in the example above.
Set up – is a verb phrase that denotes the act of putting something together.
Setup – is the noun that represents the result or arrangement of what is put together.

There cat ran away.
“there” should be “their” wrong use of the word.
