Definition & Meaning of "pettifogger"in English

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

"Pettifogger" is a slang term that dates back to the late 17th century in English, originally used to describe a lawyer who is petty, unscrupulous, or overly concerned with minor legal details. The word combines "petty" (trivial) with "fogger" (an old term for someone who obscures or confuses), emphasizing underhandedness and triviality in legal practice. It is used in informal, literary, or historical contexts, often to mock or criticize a lawyer's ethics or competence. The term is derogatory and intended to insult; it is never neutral.
