The Origin of Shrank or Shrunk

The verb shrink comes from Old English “scrincan,” meaning “to contract or become smaller.” Like many old verbs, it is irregular, which means it doesn’t follow the standard -ed pattern.

Over time, English developed different forms:

• Present: shrink
• Past: shrank
• Past participle: shrunk

The difference exists because English kept older grammar patterns instead of simplifying them. That’s why we have both shrank and shrunk today.
