Discourse markers
Discourse markers are words or phrases that help connect ideas in a text. They are usually set apart from the rest of the text with commas.
- Typically, a comma follows a phrase or adverb that introduces a sentence.
- Furthermore, many individuals experience discrimination in their workplace.
- Conversely, the rate of unemployment has decreased.
- In conclusion, it's necessary for local councils to evaluate the expenses associated with recycling programs.
- Regrettably, all the tickets were sold out.
- Likewise, animals that live outside are susceptible to infections.
Commas are also used to enclose specific words and phrases within a sentence:
- This issue, however, isn't as straightforward to resolve.
- In arid regions, like Africa, water scarcity is a significant problem.
- In cold regions, for example, Iceland, people need to allocate more funds for heating their homes.
When an adverb modifies an adjective, commas are unnecessary:
- This was accompanied by a similarly significant improvement in quality.
- However diligent you are, mistakes can still occur.
