Expert writing Tips

Best practice

When using "topic in which", ensure that the clause following "in which" provides specific and relevant information about the topic. This helps to maintain clarity and avoid vagueness. For example, instead of saying "This is a topic in which I am interested", specify the area of interest: "This is a "topic in which" the long-term impacts of globalization are examined".

Common error

Avoid using "topic in which" when a simpler prepositional phrase would suffice. For example, instead of "the "topic in which" this paper focuses", consider using "the topic of this paper" for a more concise statement.
