The Origin of Shrank or Shrunk

The words “shrank” and “shrunk” come from the verb “shrink.” This verb has roots in Old English, from the word “scrincan,” which means to contract, withdraw, or become smaller.

Over time, English verbs changed forms. Many strong verbs (like drink–drank–drunk) follow a pattern. “Shrink” follows a similar pattern:

• Base form → shrink
• Past tense → shrank
• Past participle → shrunk

This pattern is part of a group of irregular verbs in English. That’s why “shrunk” sometimes feels more natural to people—it sounds like other common forms like “drunk” or “sung.”

However, grammar rules kept both forms for different uses, which is why we still use both today.
