The Origin of Ignitor or Igniter

Both igniter and ignitor come from the verb ignite.

The word ignite comes from Latin ignire, meaning “to set on fire” or “to kindle.” It is related to the Latin word ignis, meaning fire.

English often creates nouns for people or things that perform an action by adding a suffix.

For example:

• ignite → igniter
• operate → operator
• calculate → calculator
• decorate → decorator

The spelling igniter follows the common English pattern of adding -er to a verb to describe something that performs an action.

The form ignitor follows another pattern found in English technical vocabulary, where -or is used to create nouns.

This is why both forms developed and continue to appear in written English.
