The Origin of Sneaked vs Snuck

The verb sneak means to move quietly, secretly, or without being noticed. It has been used in English since the 16th century.

sneak → sneaked → sneaked

The form snuck developed later as an irregular past-tense form. English has many verbs with irregular past forms, such as:

speak → spoke
take → took
swim → swam
sneak → snuck

Interestingly, sneaked was historically the more established form. Snuck became increasingly popular in North American English and eventually became a standard dictionary-listed form.

This explains why some speakers consider sneaked more traditional while others naturally use snuck.
