Sneaking around is an activity that involves moving quietly and stealthily in order to avoid detection. TIPTOES, SIDLES, and PROWLS are all words that can be used to describe this behavior. TIPTOES is a 7-letter word meaning to walk on one's toes in order to make as little noise as possible. SIDLES is a 6-letter word meaning to move sideways or obliquely in a quiet manner. PROWLS is a 6-letter word meaning to move around stealthily, often with the intention of hunting or searching for something. All three words can be used to describe the act of sneaking around.
