At Belekar Sirs Academy, we focus on building strong foundational language skills to help you write and speak with confidence. A common challenge for many English learners (and even native speakers) is telling the difference between words that sound alike but have very different meanings.
“Threw” and “through” are perfect examples. Because they’re pronounced the same, they’re often mixed up in writing, leading to confusing or incorrect sentences. Understanding how to use each word correctly is a small but powerful step toward mastering clear, precise English — whether for exams, professional work, or daily communication.
Introduction
“Threw” and “through” sound exactly alike, but they mean completely different things. Because they’re homophones (words that sound the same), people often mix them up in writing—even if they speak English fluently. This mix-up can lead to awkward or unclear sentences.
Knowing when to use “threw” versus “through” will make your writing clearer and more professional, whether it’s an email, essay, or quick text.

How to Remember the Difference
Quick Memory Tricks
- Threw:
It has “ew” in it — like saying “Ew! I threw it away.” Easy to link with tossing something. - Through:
Imagine “route” inside “through.” It’s about moving along a path or getting from one side to the other.
In short:
- “Threw” = action (past of throw, has “ew”).
- “Through” = movement or completion (think of a route).
Keep these simple cues in mind, and you’ll never mix them up.
Common Mistakes to Watch For
- ❌ “We walked threw the tunnel.”
✅ “We walked through the tunnel.” - ❌ “He through the ball to his friend.”
✅ “He threw the ball to his friend.” - ❌ “The report went thru several drafts.” (wrong in formal writing)
✅ “The report went through several drafts.”
Tip:
Always pause and ask — is it an action (threw) or about movement/completion (through)?
And avoid using “thru” in formal writing.
