The Origin and Background of Through or Threw

Understanding where these words came from makes them much easier to remember.

The history of through

The word through comes from Old English thurh. It has been part of English for hundreds of years. Over time, its spelling changed, but its meaning stayed almost the same.

It usually means:

• passing from one side to another
• continuing until the end
• using something as a way to reach another place

Examples:

• We drove through the mountains.
• She worked through the weekend.
• I heard the news through a friend.

The history of threw

Threw comes from the verb throw.

It is simply the past tense form.

Present tense:

I throw the ball.

Past tense:

Unlike through, this word always relates to tossing, launching, or sending something.

Examples:

• He threw his keys onto the table.
• The child threw a snowball.

Why do people confuse them?

The answer is simple.

They sound almost identical.

English has many homophones, such as:

• their / there
• hear / here
• to / too
• through / threw

When speaking, listeners understand the meaning from the sentence. But when writing, choosing the correct spelling matters.

If not, choose through.

Use threw only when describing a physical action.

Choose through.

Or ask:

Is someone throwing something?

Choose threw.

This simple check prevents one of the most common English spelling mistakes.
