When discussing a topic, it may be necessary to delve deeply and provide a comprehensive analysis. Instead of using the phrase "into detail", consider using synonyms such as "thoroughly examine", "scrutinize closely", or "explore in depth". Another option could be to describe the level of detail, such as "provide a detailed analysis", "give a comprehensive review", or "dive into the specifics". Using a varied vocabulary can make your writing or speaking more interesting and engaging, while still conveying the necessary meaning. These synonyms can help you avoid redundancy and keep your audience interested.
