Pronunciation: [kˈə͡ʊtte͡ɪl] (IPA) 
The spelling of the term "coattail" can be confusing due to its irregular pronunciation. It is pronounced /ˈkəʊt-teɪl/, with the emphasis on the first syllable. The word is made up of two parts: "coat" and "tail", which together refer to the back part of a coat that extends below the waist. The spelling of this word is often misspelled as "coat-tail" or "coat tail", but the correct spelling is "coattail".
Coattail, as a noun, refers to the extended edge or panel of fabric at the back of a coat or jacket, also known as a "tailcoat." This term is commonly used in the context of formal or elegant attire, where a coattail hangs below the waist, typically divided into two "tails," and is often associated with a tuxedo or morning suit. Historically, coattails were longer and were designed to be tied back when riding horses, preventing the coat from getting dirty or damaged.
The term "coattail" has also taken on idiomatic connotations. In political contexts, it refers to the phenomenon wherein a popular or successful candidate or political party carries other candidates to victory by virtue of their own popularity or influence. This occurs when voters are more likely to support candidates affiliated with a well-liked or victorious figure, rather than evaluating each candidate individually. The concept of riding on someone's coattails implies being propelled to success or recognition solely due to one's association with someone else.
Figuratively, "coattail" is also used to describe someone who attaches themselves or seeks to benefit from the achievements, status, or reputation of another person, without contributing much themselves. Such individuals are often criticized for lacking individuality or originality and relying on the accomplishments of others to gain attention or success.
In summary, "coattail" can refer to the physical extension of fabric at the back of a coat or jacket, as well as the political phenomenon of gaining success through association with a popular figure. It can also describe individuals who rely on the achievements of others to enhance their own status.
The word "coattail" originated in the early 17th century and comes from the combination of two words: "coat" and "tail".
The term "coat" refers to a garment that covers the upper body and is worn as outerwear. The word "tail" denotes the trailing part of an animal, such as a tail attached to the rear of a coat.
"Coattail" was initially used in a literal sense, referring to the long, trailing ends of a coat. However, over time, it acquired a figurative meaning related to politics and influence. The phrase "to ride on someone's coattails" emerged in the 19th century, metaphorically suggesting the act of benefiting or gaining advantages from someone else's success or popularity.
