Queen’s English (Let’s Sneak This In)
Is snuck a real word or should the past tense of sneak be sneaked?
While sneaked is technically the correct word in the past tense and while apparently a majority of those in the know (professors, etc.) might condemn the use of snuck as a vulgar Americanism dating back to the 19th Century, it is probably no longer considered colloquial. As is often the case in our always- changing, every-colorful tongue, by virtue of its increasing usage snuck is now nearly as acceptable as sneaked, and the preference is yours.
And while we are at it, the same might be said of the past tense of dive; dived is the technical favorite, but dove is coming on.
