Sprang vs. Sprung – Which is Correct?

Use sprang into action for the simple past: “The firefighters sprang into action.” Use sprung into action after an auxiliary: “The firefighters have sprung into action.” Both forms come from spring but have different grammatical roles. Sprang stands alone; sprung usually follows a helping verb in standard American English sentences.

Sprang or Sprung Into Action – Which is Correct?

Both “sprang” and “sprung” are correct forms of the irregular verb spring, but they are not interchangeable in the phrase “into action.” Use sprang into action when describing a completed action in the simple past. Use sprung into action when it follows a helping verb such as has, have, had, or is in an appropriate construction.

For example, “The rescue team sprang into action” is correct because sprang is the simple past tense. “The rescue team has sprung into action” is correct because sprung is the past participle following has.

The Best Trick to Remember the Difference

Use the helper-verb test: if a helping verb appears before the blank, choose sprung. If no helping verb appears and you are describing one completed past event, choose sprang.

Compare these two patterns: “The volunteers sprang into action” and “The volunteers have sprung into action.” Remember: sprang stands alone, while sprung usually needs a helper.
