The phrase "ducks in a row" is an idiom of English origin that has been in use for many years. The exact origin of the phrase is uncertain, and it is unclear whether the phrase originated from a specific event or activity or if it evolved from a common saying or nursery rhymes.
One possible origin of the phrase is associated with the natural behavior of ducks. When ducks feed, they often walk in a line behind their parent, which could have led to the phrase being used to describe an organized and tidy preparation for something. Additionally, the phrase could have evolved from the image of a mother duck leading a line of her ducklings towards water, which is a common scene in nature.
Another possible origin of the phrase is associated with the game of pool. In pool, a ball in front of a pocket is often referred to as a "duck," and to have a row of balls ready to be played is to have all your "ducks in a row." This explanation is based on the fact that pool players often use the term "ducks" to refer to particular shots in the game.
Yet another possible origin of the phrase is associated with fairgrounds and amusement parks. In these locations, there are often shooting galleries with mechanical ducks that players can hit with a single bullet. To "get your ducks in a row" in this context would mean to line up the ducklings or ducks for shooting, which would require careful的组织 and preparation.
Overall, the phrase "ducks in a row" is an idiom that has evolved from a common saying or nursery rhyme about the natural behavior of ducks or related activities such as pool and fairgrounds. The precise origin of the phrase is uncertain, but it is commonly used to describe an organized and tidy preparation for something.
