The final consonant sound is represented by /n/, while the second word "trigger" is pronounced with the initial consonant cluster /tr/ followed by the vowel sound /ɪ/ as in "sit" and ending with the consonant sound /ɡ/.

A gun trigger is a mechanical device primarily used in firearms to facilitate the release of a projectile. It serves as the mechanism that initiates the firing sequence, allowing for the discharge of a gunshot. Typically located at the rear of the firearm, it is designed to be operated by the shooter's finger.
The gun trigger is composed of several crucial components, including a spring-loaded sear, a hammer or firing pin, and a trigger blade or lever. When the shooter exerts pressure on the trigger blade, it causes the sear to disengage, releasing the hammer or firing pin. This then strikes the primer located on the ammunition, initiating the ignition sequence and propelling the projectile out of the barrel at high velocity.
The trigger is a vital safety mechanism in firearms, often featuring additional safety mechanisms to prevent accidental discharges. These safety features can include trigger locks, trigger guards, or even secondary trigger pulls or switches.
Gun triggers come in various designs to accommodate different types of firearms, such as single-action triggers, double-action triggers, and double-action-only triggers. Each design has different characteristics and requires varying amounts of pressure to engage. These variations allow for the selection of desired firearms based on individual preferences, comfort, and shooting requirements.
In summary, a gun trigger is an integral part of firearms that, when effectively manipulated, enables the release of a projectile by disengaging the sear and activating the hammer or firing pin.
The word "trigger" originates from the Middle English word "trigour", which means a device that releases or activates something. It is thought to be derived from the Old French word "trioir", meaning a lock or bolt. This Old French term has its roots in the Latin word "trochlea", referring to a small wheel or pulley. The specific use of the word "trigger" to describe the device that activates a gun or firearm can be traced back to the late 17th century.
