single-shot
Word family
Synonym discussion
Sense: adjective/1
These words all describe how often a gun can fire before it needs attention. 'Single-shot' is the narrowest: the gun holds just one round, so the user must load a new bullet by hand after every shot. 'Repeating' is broader and means the gun stores several rounds and feeds them one by one as the user works a lever or bolt. 'Semi-automatic' fires one round per trigger pull but loads the next round itself, so no hand-loading is needed between shots. 'Automatic' goes furthest: it keeps firing as long as the trigger is held. So a single-shot rifle is the slowest and simplest of the four, while an automatic rifle is the fastest. For example, a hunter might prefer a single-shot rifle for careful, one-aim shooting, whereas a target shooter often picks a semi-automatic for speed.

Etymology
This compound joins 'single', meaning just one, with 'shot'. 'Shot' began as the act of firing a weapon, then stretched to mean one attempt or one small measure of a liquid. The firearm meaning came first in the 1800s, when guns that held only one round were named for that limit. Later the same 'one and only one' idea spread to medicine (one injection), film (one continuous take), and drinks (one measure of espresso or spirit).
