sneak (verb, noun, adjective) /snik/ LISTEN
To sneak means ‘to behave as if to be unnoticed or unseen’ or ‘to behave dishonestly or secretively.’ It also means ‘to put something away or to move it in a secretive way.’ In UK English, and rather dated now, to sneak means ‘to inform on someone,’ particularly at school. As a noun, a sneak is a person who is not trustworthy or, again in dated UK English, an informer. As an adjective, sneak refers to something done without warning or without being seen.

In pop culture
A sneak peek or sneak preview is a brief, secretive look at something, especially an opportunity to see something before it is officially available, so it might be a very short clip of a movie that is coming out soon, a short article on some features of new software, or perhaps a short extract from a forthcoming novel. It can also be a showing of a movie before it is officially released. Here is the sneak peek of the most recent Doctor Who Christmas special:

sneakiness (noun), sneaky (adjective), sneakily (adverb)
Though sneak first appeared in the mid-16th century (in the first written example we have, it is implied in the adjective sneakish), it is thought to be a variant of the Middle English snicken, which comes from the Old English snīcan, meaning ‘to creep.’ It can be traced back to the Proto-Germanic verb sneikanan, and the Proto-Indo-European root sneg-, which could mean ‘to crawl’ as well as ‘a creeping or crawling thing,’ and is the root of the word snake. The noun comes from the verb and first appeared in the mid-17th century, while its use as an adjective dates back to the late 18th century.
