Pronunciation: [pˈə͡ʊstənz] (IPA) 
Posterns is a plural noun referring to the back or side entrance of a building or fortress. The spelling of this word may confuse some due to the silent "r" in the middle. However, using IPA phonetic transcription, we can see that the "r" is there to indicate a syllabic consonant. The correct pronunciation is /ˈpɒstənz/, with the stress on the first syllable. This word is derived from the French word "posterne," meaning "back door."
Posterns are small, concealed, and typically secondary entrances or gates located in the walls of fortifications, castles, or other fortified structures. These discreet passageways serve as an alternative means of entry or exit that is less visible and vulnerable to attack compared to the main entrance. Posterns are strategically designed to provide a covert and restricted access point.
The term "postern" is derived from the French word "posterne," which in turn stems from the Latin word "posterula," meaning "a little entrance" or "small gate." Posterns are often positioned in less fortified areas or in locations where the terrain provides natural cover or concealment, such as along the side or rear walls of a fortress. They may also be found in locations that lead to the outside of the fortification, enabling discreet communication or escape routes during times of siege or other threatening situations.
Typically, posterns are narrow passageways that can accommodate only one person at a time, sometimes requiring individuals to stoop or crouch to pass through. They may include additional security features such as hidden or locking mechanisms, secret passages, or hidden chambers. Posterns can offer a strategic advantage by allowing for clandestine movements, surprise attacks, or rapid escape in times of danger. However, their concealed nature also requires caution and vigilant monitoring to ensure they are not exploited by unwanted intruders.
The word "posterns" is derived from the Old French word "posterne", which emerged in the 14th century. "Posterne" itself came from the Late Latin word "posterula", meaning a small back door or gate. The Latin term was a diminutive of "posterus", which meant "coming after" or "behind". This ultimately traces back to the Latin word "post", meaning "behind" or "after". Therefore, the etymology of "posterns" reveals its association with small rear entrances or gates.
