The term "king post" is commonly used in architecture and engineering to describe a vertical post that supports the centerline of a roof truss. Interestingly, the spelling of this term is quite simple and straightforward. The word "king" is pronounced with the /kɪŋ/ sound, followed by the word "post" pronounced with the /poʊst/ sound. Together, the two words are spelled exactly as they are pronounced, making them easy to remember and understand for those in the construction and design industries.
A king post is a vertical structural component that is commonly used in construction and engineering to support the weight of a roof or a bridge. It is typically a single wooden or metal post that extends from the roof ridge or the bridge centerline to the horizontal beam below, providing a central vertical support for the structure.
The king post is positioned in the middle of the span or the structure to evenly distribute the load and maintain stability. It acts as a primary load-bearing member that carries the weight of the roof or the bridge and transfers it to the supporting walls or columns. This vertical post also helps to counteract the effect of sagging or excessive deflection in the structure, thereby maintaining its integrity.
In addition to its load-bearing function, a king post can often be embellished with ornamental designs or decorative shapes to enhance the aesthetic appeal of a structure. The material used for constructing a king post can vary based on the specific requirements of the project, with wood being commonly used for its flexibility, strength, and cost-effectiveness, while metal can be employed for its durability and resistance to elements.
Overall, a king post is an essential architectural element that provides crucial structural support and stability, making it an indispensable component in the construction of roofs and bridges.
The middle post of a roof standing on the tie-beam, and reaching up to the ridge, also called crown-post.

The term "king post" originated in Middle English, around the 14th century. It is believed to have derived from the combination of two Old English words:
1. "King" comes from the Old English word "cyning" which means a ruler, leader, or monarch. This word is also related to the Old High German word "kuning" and Old Norse word "konungr", both meaning king.
2. "Post" comes from the Old English word "post", which refers to a pillar or vertical support structure.
Therefore, the term "king post" refers to a central vertical post or column that supports the weight of a structure, often in the construction of a roof or bridge. It is called a "king post" due to the significance of its central and supporting role, resembling the importance of a monarch or king within a hierarchical structure.
