Homophones are a common cause of confusion in the English language. You have two words that belong to two different parts of speech or are derived from different words, and you unknowingly use them interchangeably in a sentence.

Threw vs Through

“Threw” is the past tense of the verb “throw” which means to propel something with force, while “through” is a preposition which means moving in one side and out of the other side of an object or an area. Example: “He threw the ball” vs “He walked through the door.”

Threw vs Through

Examples: 1) Lily ‘threw’ a brick on Adam’s face that he got unconscious. 2) People were going ‘through’ no entry.

Threw and through are pronounced the same, yet their meaning is as different as chalk and cheese.

When to Use Threw?

Threw is a verb that acts as the past tense of throw. When you’re talking about propelling something in the air by a great amount of force, you’re talking about throwing it.

Now when you report the same statement in the past, the right verb to use is ‘threw.’


  1. She threw the ball at him
  2. The monkey threw back his hat.

All these example statements are reporting in the past. Threw could also mean to dislodge, to make pottery, to cast a dice, or to lose deliberately.

It’s believed that the word throw, the present tense of the verb threw, was coined from the word throwen — a middle English word that meant to twist, hurl, or wring.

It’s then that the past tense ‘threw’ would be derived from the past tense of the same word, thrawan.


When to Use Through?

Through is an adverb that also doubles as a preposition and adjective. The word is usually used to indicate entering from one side and exiting from the other.

So when something enters into something and then exits it from the other side, then you can say that it’s gone through.

Through can also be used to suggest a passage. It’s also used to indicate task completion or that something has moved from one point to another. Other than that, ‘through’ can also be used to mean something is running nonstop.

As an adjective, ‘through’ is used to mean the item or tool being used or the cause of something.

Again, the word through is believed to have evolved from a Middle English word, thruhg or thurg, which came from an ancient English word thurh. Both words bear the same meaning as through.

Examples in a sentence:

1) The boy threw the ball at her sister.

Threw is used in this sentence to mean hurl.

2) Kevin walked through the shop to their backyard, where he found his father attending to their flock.

 ‘Through’ is used in this sense to refer to a passage. It means that Kevin entered the shop from the front end and left it using an exit door at the back.

 3) If you wouldn’t be through with your work when the bell rings, then you won’t be going out for short break.

Here, through is used to mean finish or complete. What’s being implied is that if by any chance the subject won’t have completed the assigned work, then they won’t be going out for the short break.

4) Thought you were through with school.

In this sentence, ‘through’ is used to mean finish. The person making the statement is simply wondering why the subject hasn’t finished school yet.

5) She learned about the job through Facebook.

Here, though is used to mean “as a result of.”


Main Differences Between Threw and Through

  1. The words threw and through are two parallel words that only share the same pronunciation and nothing else.
  2. The two words cannot be used interchangeably, and that’s because they bear two totally different meanings that are not in any way connected.
  3. ‘Through’ is used in reference to motion or passage. It can also be used to mean finishing something or getting done with work or a particular project.
  4. Contrariwise, people use ‘threw’ to indicate hurling. It means launching something by hand or using a catapult.


  1. The despicable boy threw a mug at her mother before escaping through the back door.
  2. He threw the party through his elder brother.

From these two examples, it can be noted that the two words bear a series of meanings that differ from each other depending on the message being passed across.

In the first sentence, ‘threw’ is used to mean ‘propel.’ The mug was propelled towards the mother. In the same sentence, through is used to mean ‘from.’

In the second case, however, ‘threw’ is used idiomatically to mean ‘organize’ or ‘to hold,’ while through is used to mean ‘by way of.’

Idiomatic Use of Threw

Threw can be used idiomatically to mean different things. For instance:

1) Threw a monkey wrench, which means to sabotage something.

2) Threw cold water on, which means discourage.

Her mother’s remarks threw cold water into her ambitions.

3) Threw oneself at, which means to try so hard to win someone’s affection.

It’s a well-known fact that the bride threw herself at the best man.

4) Threw oneself into, which means to try something vigorously.

Idiomatic Use of Through

‘Through’ also boasts a series of idiomatic use. They include:

1) through and through, which means complete.

She’s a staunch Manchester United fan, through and through.

2) Go through with something, which means to continue or see something to completion.
