How to choose: Which or That

When should you use 'that' or 'which' in a sentence?  I find it difficult figuring out if I used it appropriately.  According to Shundalyn Allen, Grammarly blog writer it's simple, see below for details.

• In a defining clause, use that.
• In non-defining clauses, use which.
• Remember, which is as disposable as a sandwich bag. If you can remove the clause without destroying the meaning of the sentence, the clause is nonessential, and you can use which.
• After reading the blog, it's now easier for me to remember when to use either of them.  I should use 'which' if the information is a non-defining clause.  This means if you took 'which' away, it wouldn't affect the meaning of the sentence.  See the two examples from the blog below to get a better understanding:
• My bike that has a broken seat is in the garage.   'That' is essential to the meaning of the sentence, without it, you wouldn't know if this person meant this particular bike or another bike.

My bike, which has a broken seat, is in the garage. 'Which'  is non-essential to the meaning of the sentence. Without 'which' you would still know that the bike with the broken seat is in the garage.

Whose vs Who's

Whose vs Who's

     I see these two on the internet missed used by people.  Who's is a contraction of who is or who has. Whose is a possessive form of who, as in who did it? Whom is where the word comes from meaning to need more information.

• Both who’s and whose come from the pronoun who.
• 
  

Who's-

• 
  
• Who’s is a contraction, meaning it’s two words stuck together. The formula: who + is, or who + has.
• 
  
• For example: who’s hungry?

Whose-

• 
  
• Whose is a possessive pronoun. Use it when you’re asking (or telling) whom something belongs to.
• 
  
• For example: whose sandwich is this?

•

Which vs. Witch

Which vs. Witch

 A grammar mistake I have seen made is using which and witch. I don’t have an issue with this, but it seems to be a problem for others. I found an article the shows the difference between the two.

Which  - pronoun

1.       Which of these do you want?

2.       Choose which appeals to you.

3.       The book, which I read last night, was exciting.

Witch  - noun
A person that practices magic.

1.     The witches were in black robes and pointed hats.
2.       The witch practices magic.

difference between content and context

We will start with the meaning of context. The meaning of “context” according to the Oxford Dictionary is-
“The parts of something written or spoken that immediately precede and follow a word or passage and clarify its meaning:” 

Then next you have content. The meaning of content is The meaning of “content” according to the Oxford Dictionary is-

“willing to accept something; satisfied” and “subject matter or topic in a written document”.

The difference between the two words is that context means we are making a reference to a specific event or occasion. The main difference is that “content” and “context” is that you “refer to a context” and you “write the content”. From reading the article that is the best difference from it. https://www.differvs.com/difference-content-context/

Farther vs Further

One common grammar mistake I've seen is the use of farther vs. further. It seems to be tricky to figure out which word to use in certain situations. The AP style guide clears up the differences in the two.

Farther is referring to physical distance.
     Examples:
                         I can run farther now that I have lost weight.
                         I want to move farther away from the city.

Further is referring to an extension of time or degree.
     Examples:
                          If we are still having issues with connectivity, I will look further into
                          network settings.
                          Nothing could be further from the truth.

Active and passive voice

Active and passive voice

Voice shows whether the subject acts (active voice) or is acted on (passive voice)—that is, whether the subject performs or receives the action of the verb. Only transitive verbs are said to have voice. The clause the judge levied a $50 fine is in the active voice because the subject judge is acting. But the tree’s branch was broken by the storm is in the passive voice because the subject branch does not break itself—it is acted on by the object storm. 

The passive voice is always formed by joining an inflected form of be (or, in colloquial usage, get) with the verb’s past participle. Compare the ox pulls the cart (active voice) with the cart is pulled by the ox (passive voice). A passive-voice verb in a modifying phrase often has an implied be-verb: in the advice given by the novelist, the implied (or understood) words that was come before given; so the passive construction is was given. Although the be-verb is sometimes implied, the past participle must always be expressed. Sometimes the agent isn’t named {his tires were slashed}. As a matter of style, passive voice {the matter will be given careful consideration} is typically, though not always, inferior to active voice {we will consider the matter carefully}. The choice between active and passive voice may depend on which point of view is desired. For instance, the mouse was caught by the cat describes the mouse’s experience, whereas the cat caught the mouse describes the cat’s.

There, Their, and They're

One of the mistakes that I pick up on commonly is the misuse of There, Their, They're. This deadly trio has tripped up writers of all aptitudes and positions. I've made this mistake more than once in my career, usually in haste. The problem with these words is they're homophonous, and of similar sound and pronunciation with differentiation in meaning.

What is the difference?

There - adverb

1. In or at that place. (opposed to here)
2. At that point in an action, speech, etc. 
3. In that matter, particular, or respect.

examples:

• There is an inherent danger in flying; nevertheless most of the time it is safer than driving.
•  He must stand there in the corner until he apologizes for his rude behavior. 

Their - pronoun

1. A form of the possessive case of they used as an attributive adjective, before a noun.
2. Used with a singular indefinite pronoun or singular noun antecedent in place of the definite masculine his or the definite feminine her.

examples: 

• They left their car lights on, should we let them know?
• It's good for teachers to have high expectations for their students.

They're - contraction

1. The result of contracting or combining the terms they and are.

examples:

• You think they're in there?
• Don't worry, they're tamer than they look.
