That or Which

Many students make grammatical mistakes even when they are in colleges and universities. This especially happens while writing a masters dissertation for the final degree. Due to the lack of English language skills, many students, especially the one who come to the United Kingdom from different parts of the world consider buying dissertations online as an alternative option fearing low grades due to their English grammatical issues.

Making a grammatical mistake shows off your lack of proficiency in your language. In the primary classes, you are taught how not to make a grammatical mistake. In the middle classes, you are asked not to do so. In high school, your grades are deducted and the sole reason is the grammatical mistakes. In colleges and universities, you have to be extra careful as grammatical mistakes can lead to the loss of a degree.

Even if grammatical mistakes mean a lot, the majority of students don’t pay any heed to it and the result is that they can neither get a good degree nor a good job. Many students of science subjects believe that grammatical mistakes don’t need any consideration when they are writing about the cell structure, expressions of equations, or law of motion. The spellings are often messed up and there is no good sentence structure in the assignments. Indeed, you don’t have to pay a lot of heed to grammar in science subjects. The professors don’t care about it as you are having a lot of hard-time to learn about the science of life.

In the subjects of literature, arts, and humanities, grammar is important for the students to care about and the professors are often seemed to be strict about it. The students try to learn up-to-date grammar tricks to improve themselves and have no mistakes in the paper as the grammar will be checked by the professors. These tips and tricks are not helpful as some tricks are too difficult that the students forget about the previous rules of grammar.

Scrolling down, you are going to be introduced to a common grammatical mistake that has become a part of our routine and we see it nearly everywhere. This “everywhere” can extend from undergraduate essays to professional publications like newspapers, magazines, and even the most popular novels.

Which and That

Which and That has become a habit and many professional writers as well use them without having any consideration to their use and grammatical rules. Many people have the lame thought that these two words can be used at the place of each other, but you are at fault.

You have to know about the grammatical rules that separate both terms from each other.

“That” is a restrictive pronoun.

Many readers may be confused about the restrictive pronoun. Consider this example,

“This is the hat that I wore to the wedding.”

According to Grammarly,

“A restrictive clause modifies the noun that precedes it essentially.”

Restrictive clauses often provide you the deep information about a particular sentence. In American English, “that” is used to introduce restrictive clauses and which introduces non-restrictive clauses. In British English, “that” and “which” are used interchangeably.

“That” is important to the noun which is under consideration.

In the above-given example, the hat was worn at the wedding and the “that” defines the character of the hat. You might have a lot of hats in your home. But, there was a specific hat which you wore at the wedding. “That” will help you to identify it.

Take this example,

“My bike that has a broken handle is in the garage.”

Now, the speaker has several bikes and he/she is referring to the bike that has a broken handle. Remove the clause, “that has a broken handle” and we have the sentence as,

“My bike is in the garage.”

At this point, the speaker is implicating the bike only and you would get the meaning of the fact that the speaker has only one bike and that it is in the garage. Now, if the speaker adds the clause, you would be able to know that there might be more bikes and that; one of the bikes has a broken handle.

So, this was about “that”.

Now, we have to consider “which”.

“Which” is used as a non-restrictive pronoun. It won’t affect the structure of your sentence and you don’t have to use the clause. And, if you use it, it won’t be a mistake. But, the condition here is that the second clause must be non-essential if you are about to use “which”.

Consider this example,

“The old schoolhouse, which is one of my favorite historical sites to visit, is in dire need of renovation.”

You can give up on the clause, “which is one of my favorite historical sites to visit” and the sentence would give the same meaning.

“The old schoolhouse is in dire need of renovation”.

Your reader and listener will get your point of view and then, later on, you can tell them that it is your favorite place.


If you want to use a trick to remember the difference between these two, you can have a look at it.

According to ProWritingAid,

“If your sentence has a clause but does not need it, use “which”; if the sentence does need the clause, use “that.”
