Introduction
“Ignitor” and “igniter” are two terms that look almost identical and are often used interchangeably, but some contexts prefer one spelling over the other. Both refer to devices that start a fire or initiate combustion, but the spelling difference can vary based on industry or region.
Although they sound similar, ignitor and igniter serve the same basic purpose: starting a flame. Understanding the difference helps ensure proper usage in technical writing, manuals, and everyday conversation.
In this article, you’ll learn their definitions, usage rules, examples, a comparison table, real-life dialogues, and tips for remembering which spelling to use.
What Is “Ignitor”?
Ignitor is a noun that refers to a device or component that initiates ignition, usually in technical or engineering contexts.

- “The furnace ignitor failed, so the heater wouldn’t start.”
- “Pyrotechnicians use an electric ignitor to light fireworks safely.”
Where It’s Used:
- Automotive industry
- Gas appliances (heaters, stoves, furnaces)
- Fireworks and pyrotechnics
Tip: Ignitor = often used in technical or formal engineering contexts.
What Is “Igniter”?
Igniter is also a noun with the same core meaning: a device that starts combustion.
Meaning:
- A tool or device that lights a flame
- Often interchangeable with “ignitor”
Examples:
- “The barbecue lighter works as an igniter.”
- “The rocket’s igniter was tested before launch.”
- “Always handle the igniter carefully to avoid accidents.”
Where It’s Used:
- Household appliances (barbecues, stoves)
- Rockets and scientific experiments
- General usage in both technical and informal contexts
Tip: Igniter = more common in everyday usage.
Key Differences Between Ignitor and Igniter
| Feature | Ignitor | Igniter |
