Stop (verb) means to cease moving or doing something, or to prevent something from happening. As a noun, a stop is a place where a vehicle halts to let passengers on or off, or a short break during a journey.
What Does Stop Mean?
Stop comes from Old English stoppian meaning "to plug" or "to close up", which itself derives from West Germanic stoppōn related to Old High German stopfōn ("to cram" or "to stuff"). The original sense was about physically blocking or plugging an opening. By Middle English the meaning had broadened to include ceasing any kind of movement or action — the sense we use most commonly today.
As a verb, stop is extremely versatile. It can be intransitive ("The train stopped") or transitive ("She stopped the car"). It can express your own choice to cease ("I stopped working at six") or the prevention of something ("Nothing can stop us now"). It also appears in fixed phrases and idioms: stop at nothing, stop short of, stop dead in your tracks.
As a noun, stop is perhaps best known in the compound bus stop — a place where buses pause for passengers. In British English a full stop is the punctuation mark (.) used at the end of a sentence, which Americans call a period. A pit stop is a brief halt for repairs or refuelling in motor racing, and the word is used more broadly for any quick break.

Usage Notes
Stop + Gerund vs Stop + Infinitive
This is one of the most tested grammar points at B1–B2 level. The two patterns have completely different meanings:
Stop + gerund — the action itself ends: "She stopped talking." (She was talking; now she is not.)
Stop + to-infinitive — you pause in order to do something else: "She stopped to talk to her friend." (She paused her current activity and began talking.)
The verb stop cannot be followed directly by an infinitive without the meaning shifting as described above. When you want to express prevention, use the pattern stop + object + from + gerund: "The fence stops children from running into the road."
