Usage
The standard past form of sneak is sneaked. An alternative past form, snuck, arose in US dialect in the 19th century. Although snuck was formerly regarded as non-standard its use has spread in the US, where it is now regarded as a standard alternative to sneaked in all but the most formal contexts.
Etymology
C16: prob. dial.; perh. rel. to obs. snike ‘to creep’.
