Abatis is a military term used to describe a defensive barrier made of trees and branches. The spelling of this word can be confusing because it is not pronounced phonetically. The correct pronunciation is /ˈæbəti/ (ab-uh-tee). The "a" is pronounced as in "cat," the "b" and "t" are pronounced as usual, and the emphasis is on the second syllable. The "s" at the end of the word is silent. It is important to properly spell and pronounce military terms to avoid confusion and miscommunication.
An "abatis" is a military obstacle or defensive structure typically designed to impede the advance of an enemy force. It consists of a barricade made up of felled trees, usually with their sharpened branches pointing outwards. This arrangement creates a formidable obstacle that is difficult for an enemy to penetrate or climb over.
The term "abatis" originates from the French word "abbattre," meaning "to fell" or "to knock down." This accurately describes the process of constructing an abatis, as it involves cutting down trees and arranging them strategically to form a defensive barrier. Usually, the trunks are arranged parallel to each other, creating a solid wall-like structure, while the branches are positioned in a crisscross pattern, facing outwards.
The primary purpose of an abatis is to slow down or hinder enemy troops, as the dense tangle of tree trunks and branches can significantly impede their progress. It can also provide cover for defending forces, making it difficult for attackers to approach or breach the defensive line. Additionally, abatis can be enhanced by incorporating other defensive elements such as barbed wire, entrenchments, or trenches, further augmenting their effectiveness.
Abatis have been widely utilized throughout history, particularly during times when natural barriers such as forests were available or strategically created. Their usage can be traced back to ancient civilizations, and they continue to be employed in modern military tactics, albeit with variations in design and materials.
Piles of trees or their larger branches, with sharpened points outward, laid down for the protection of troops.

The word "abatis" derives from the French word "abattis", which means "a felled tree" or "a mass of fallen trees and branches". This French term, in turn, originates from the verb "abattre", meaning "to fell" or "to strike down". "Abatis" has been used in English since the 17th century to refer to an obstacle in warfare composed of felled trees, sharpened branches, and other debris, placed with their branches facing the enemy to impede their advance. Over time, the term has also come to describe any similar defensive obstruction or barricade.
