Origin and Etymology

The verb shrink comes from Old English scrincan, meaning:

• to contract
• to become smaller
• to draw back

The word has Germanic roots and is related to similar words in Dutch and German.

Over centuries, English preserved multiple forms of the verb:

• shrink
• shrank
• shrunk

This pattern resembles other strong verbs such as:

• sing → sang → sung
• drink → drank → drunk
• ring → rang → rung

Because of this historical development, English maintains separate past and past participle forms.
