To go over with a fine-tooth comb means to carefully examine or scrutinize something in a thorough and meticulous manner. It suggests a diligent and methodical review of details, typically searching for errors, inconsistencies, or hidden elements. This expression derives from the fine-tooth comb, a tool with narrow and closely spaced teeth that is used to untangle hair and remove any small debris.
When applied figuratively, going over with a fine-tooth comb implies a painstaking investigation, typically conducted to find mistakes, uncover hidden issues, or ensure completeness. It involves an exhaustive analysis of all aspects, leaving no stone unturned. This expression is commonly used in contexts like proofreading documents, inspecting records, investigating crimes, auditing financial statements, or conducting highly detailed research.
The phrase implies a critical approach, where the focus is on meticulous scrutiny rather than a quick or superficial examination. It conveys a sense of thoroughness, patience, and attention to detail. By meticulously inspecting every aspect of the subject at hand, potential problems, flaws, or areas for improvement can be identified, leading to enhanced accuracy, quality, and reliability. Therefore, going over with a fine-tooth comb often serves as a metaphor for conducting a thorough review, ensuring precision, and achieving a comprehensive understanding of a given topic.
