The word "chutzpah" is primarily a Yiddish word "khutspe", though it originates from Hebrew, which may have borrowed it from the Aramaic word ḥu ṣpā.  It has since been adopted into English, but retains its Yiddish roots.  In Yiddish, "chutzpah" describes a quality of audacity, gall, impudence, or brazen confidence, often in a negative way. In English, it's often seen as a positive trait, emphasizing boldness and courage. 

The word "chutzpah" entered the English language sometime between 1890 and 1895.  

Examples of chutzpah used in a sentence:
