Definition & Meaning of "sneak thief"in English

What is the origin of the term "sneak thief" and how is it used?

"Sneak thief" is a slang term used to describe a person who steals stealthily, often in a petty or cowardly manner. It combines "sneak" (to move furtively or secretly) with "thief" (someone who steals), emphasizing the stealthy, underhanded nature of the crime. The term has been used in English since at least the 18th century, appearing in criminal reports, literature, and everyday speech to distinguish quiet, opportunistic theft from brazen or violent robbery. It is derogatory, used to condemn both the act and the character of the person, and carries a clear moral judgment.
