Stylometry is the forensic‑linguistic practice of identifying authorship by analysing “style markers”—the habitual and usually unconscious linguistic choices that give a text its consistency and distinctiveness. In forensic work it is applied to author identification, plagiarism detection, and other forms of authorship analysis, often using statistical or computational methods to compare texts (e.g., pair‑wise contrasts of text‑message data). The approach is presented as promising but “difficult to settle” because individual style is hard to pin down, and scholars such as Grant and McMenamin call for further research to “strengthen the science.” Consequently, stylometric findings must be presented cautiously, acknowledging the limits of certainty required in legal contexts.
