Smelled or Smelt: What’s the Difference?

Irregular verbs are tricky for the native and nonnative writer alike. Irregular verbs are verbs that don’t take on the typical past tense spelling pattern, and English has a lot of them.

Talk is an example of a regular verb. It changes from present tense to past tense by adding an “ed” to the end of the word.

  • I talk.
  • I talked.

Drive is an example of an irregular verb. It completely changes when it forms the past tense.

  • I drive.
  • I drove.

The verb smell actually has both a regular and irregular past tense form.

  • I smell. (Present)
  • I smelt. (Past)
  • I smelled. (Past)

Both of these forms are correct, but they’re not always interchangeable. Sound confusing? Don’t worry. I’ll explain everything you need to know about smelt vs. smelled below.
