Threw and through sound the same, but they do not mean the same thing. That is why this pair causes so many writing mistakes.
Use threw when you mean someone tossed, launched, caused, or suddenly moved something in the past. Use through when you mean movement from one side to another, progress from start to finish, a time range, a method, or being finished.
The easiest way to remember the difference is this: threw is an action from throw, while through usually shows passage, completion, or connection.
Quick Answer
Threw is the past tense of the verb throw.
Example:
She threw the ball across the yard.
Through is usually a preposition, adverb, or adjective. It often means from one side to the other, from start to finish, by means of, or finished.
Example:
We walked through the park after lunch.
Do not use through when you mean tossed. Do not use threw when you mean passage, time, completion, or method.
Why People Confuse Them
People confuse threw and through because they are pronounced the same in standard American English: throo.
The sound does not tell you which spelling to choose. The sentence meaning does.
If the sentence has a past action related to tossing, moving forcefully, causing, or hosting, use threw. If the sentence shows movement, progress, time, access, or completion, use through.
Compare these two sentences:
She threw the keys on the table.
She walked through the door.
The first sentence needs an action verb. The second sentence needs a word that shows movement from one place to another.

Meaning and Usage Difference
Threw always connects to the verb throw. It can mean tossed something with the hand, moved something forcefully, caused a sudden state, hosted an event, or rejected something in a phrase like threw out.

Tone, Context, and Formality
Both threw and through are standard words in American English. Neither one is more formal by itself. The correct choice depends on grammar and meaning, not tone.
Threw feels natural in action sentences:
The pitcher threw a fastball.
My brother threw his backpack on the couch.
Through feels natural when the sentence needs movement, access, time, means, or completion:
The hikers moved through the forest.
We worked through the weekend.
The message came through email.
I am finally through with the report.
In careful writing, do not replace through with threw just because they sound alike.
Which One Should You Use?
Use threw if the sentence answers “What did someone do?” and the action is related to throwing, moving, causing, or hosting.
Use through if the sentence answers “Where did it go?”, “How did it happen?”, “How long did it last?”, or “Is it finished?”
Here is a compact comparison:
• Threw: past action — tossed, hurled, flung, hosted, caused.
• Through: passage or completion — across a space, during a time, by a method, all the way, finished.
A quick test helps:
If you can replace the word with tossed, use threw.
If you can replace it with from one side to the other or finished, use through.
