General prefixes:
* Un-: This is a common prefix for creating antonyms, but it doesn't always work well with verbs. "Uncontinue" sounds awkward.
* Dis-: This can sometimes be used for verbs, but it might not be the best fit for "continue" as it usually implies a separation or a lack of something.
* Non-: This prefix is often used for adjectives and nouns, making "non-continuation" a possible option, but it's not a common verb form.
Context-specific prefixes:
* Stop: "Stop continuing" is a direct and clear way to express the idea of not continuing.
* Cease: "Cease continuing" is a more formal way to express the same idea.
* Suspend: "Suspend continuing" implies a temporary halt, not a complete cessation.
* Terminate: "Terminate continuing" suggests a more final end to the action.
Phrases:
* No longer continue: This is a simple and straightforward way to express the idea.
* Discontinue: This is a common and widely understood verb that means to stop continuing.
Ultimately, the best way to express "not continue" depends on the specific context and the desired tone of your writing. Choose the option that is most clear, concise, and appropriate for your audience.
