Ignitor or Igniter: Which Is Correct?
Updated · Which One Is Correct editorial team
Quick answer: Both ignitor and igniter are acceptable spellings for a device that starts a flame or combustion process. However, igniter is generally preferred in American English, while ignitor appears frequently in technical manuals. You can use either without being considered incorrect.
The Short Answer
Igniter is the standard and most common spelling in general American English, though ignitor is also widely accepted, particularly in engineering contexts. Both words refer to the same device used to initiate combustion.
People confuse them because the root verb ignite naturally suggests a -er suffix for the agent, just like baker or writer. The -or variant persists due to historical influence from Latin-derived words and specific industry standards that favor that ending.
