The word "snuck" is a past tense and past participle form of the verb "sneak". The term "sneak" can be traced back to Middle English, where it developed from the word "sniken", meaning to creep or crawl. This Middle English term ultimately originated from the Old English word "snician", which had a similar meaning of moving in a stealthy or secretive manner. Over time, the word "sneak" came to represent the act of moving quietly and furtively, and "snuck" emerged as an irregular past tense form, often used in colloquial or informal contexts, particularly in North America.
