- Implement semicolons to join closely related independent clauses (The hypothesis was confirmed; the results were statistically significant)
- Employ colons to introduce lists or explanations (The study examined three variables: temperature, pressure, and humidity)

It enriches the text by adding depth and understanding, allowing readers to grasp nuances that may not be immediately apparent. This can be especially important in writing where clarification of thoughts enhances comprehension and engagement.
Aside: An aside is a dramatic device used in literature and theater where a character speaks directly to the audience, revealing thoughts or feelings that other characters on stage are not aware of. This technique creates a connection between the speaker and the audience, offering insight into the character's inner world while advancing the narrative.
Clarification: Clarification is the process of making information clear and understandable, often through explanation or elaboration. It is crucial for effective communication, as it ensures that ideas are conveyed accurately and comprehensively, reducing confusion and misinterpretation. Clarification can take various forms, such as rephrasing, providing examples, or using visual aids to enhance comprehension.
Clarifying parenthetical statements: Clarifying parenthetical statements are phrases or clauses set off by dashes or parentheses that provide additional information or clarification without interrupting the main flow of a sentence. These statements help readers understand context, offer examples, or specify details that enhance the primary message being conveyed.
