USAGE
The word meaning 'look quickly or furtively' and 'a quick or furtive look' is peek, not peak： the sun peeks out only intermittently, a sneak peek at what's in store. In some contexts this error is very common: for example, almost a third of citations for the expression a sneak peek in the Oxford English Corpus are for the incorrect spelling.
词源
late Middle English pike, pyke, of unknown origin.
