Use a space after the comma, not before. This article is about a few of the common grammatical errors in writing.
The Apostrophe Confusion: Your vs. You’re; It’s vs. Its; There vs. Their. The confusion comes from the fact that apostrophe can be used to show ownership as well as to denote contraction. Words like his, hers, its and theirs are possessive pronouns. They have possession built into them already, so they do not need apostrophes.
The house over there is theirs, not yours.(no apostrophe in theirs or yours).
Possessive forms of the pronoun ‘it’ does not use an apostrophe, while the verb contractions do use apostrophes.
It’s a beautiful cat. Its hair is long and shiny.
Whose cat is that? Who’s coming to pick it up?
Contractions like they’re is often confused with their, and you’re is confused with the possessive your.
It is quite common to find two independent clauses joined without punctuation or a conjunction. An independent clause is a complete sentence, with both subject and verb. When connecting two independent clauses, some form of punctuation and/or a conjunction (and/while/but/because…) is required.
The man walked along the road he felt tired. (incorrect)
A Period required after ‘road’. So the corrected forms could be:
The man walked along the road. He felt tired.
The man walked along the road, and he felt tired.
When the cars raced by we cheered it was an exciting race.
Should be corrected as:
We cheered when the cars raced by, and/as it was an exciting race.
The confusion occurs because ‘lay’ is the past tense form of ‘lie’. The simple past, continuous, and past perfect tenses of the pairs of words are:
lie: lie, lying, lay, (have) lain;
lay: lay, laying, laid, (have) laid
The following sentences illustrate the correct and incorrect uses of lay and lie.
I lie (not lay) on the bed when I listen to my favorite music. I lay on the bed while I listened to my favorite music.
I am lying [not laying] on the floor watching television. I am laying my briefcase on my desk.
Yesterday I lay in bed all day with a fever. Yesterday I laid my briefcase on my desk.
Affect/Effect: To affect some thing is to have some influence upon it. To effect some action is to cause it to happen.
I was affected by the stinging remarks of my friend. It had a strange effect on me.
If one thing complements another, then each of them completes the other, and the two together make a whole. In contrast, the word “compliment” is an observation of some good quality in a person.
The word, “loose,” means something is not tight or securely fastened down. It might easily fall apart or fall off. The word “lose,” in contrast, means to have something go away and become lost.
