The phrase "was on one's tail" is an idiomatic expression that originated from the field of aviation, particularly during aerial combat. To understand its meaning, it's important to first define its key elements.
The term "tail" refers to the rear section of an aircraft, including its vertical stabilizer and rudder. In any combat scenario involving airplanes, being "on someone's tail" means positioning one's aircraft directly behind an opponent's, often with the intent to pursue or engage in an attack.
In broader usage, the phrase "was on one's tail" has come to signify a situation where someone is closely following, pursuing, or targeting another person or object with determination. It suggests a context of close pursuit or pressure, implying that the pursuer is just one step behind the person or object they are chasing.
The phrase is commonly used metaphorically in non-aviation contexts to describe situations where individuals or entities are relentlessly chasing or pursuing someone. For example, in a sports competition, it may describe a situation where one team is dominating play and maintaining constant pressure on their opponents. Similarly, in a business context, the phrase could be used to portray a determined competitor relentlessly pursuing a company's market share.
In essence, "was on one's tail" metaphorically conveys a sense of relentless pursuit, whether it be physical or symbolic, highlighting the idea of being closely followed or pursued by someone or something.
