The term "rat on" originates from the behavior exhibited by rats, which are known for their survival instincts and tendency to alert others about potential threats. The phrase has been adopted into everyday language to describe situations where individuals act like informants or betrayal, disregarding loyalty, trust, and camaraderie. Consequently, "rat on" is often associated with negative connotations, as it involves exposing someone's wrongdoing or providing information that leads to harm or punishment for another individual.
The phrase "rat on" is derived from the noun "rat" and the preposition "on". The word "rat" originated from the Old English "ræt" or "raett", which can be traced back to the Proto-Germanic word "rattus". It is believed to have further influenced words in various Germanic languages, such as German "Ratte" and Dutch "rat". In the early 19th century, "rat" began to be associated with people who betray or inform on others, referring to the behavior of rats historically known for their perceived treacherous habits. Around the same time, the phrase "rat on" emerged, indicating the act of informing against someone or reporting them to authorities.
