This commentary takes note of the existence of "tortured phrases" (i.e. unspecific jargon or confusing alternative phrases), as indexed in the Tortured Phrases Detector of the Problematic Paper Screener (PPS) (sourced on January 10, 2023) in 213 preprints, 13 of which are related to COVID-19. Select "tortured phrases" in 11 preprints are highlighted, to offer readers an appreciation of this phenomenon. The incorrect representation of jargon in the medical and health literature may risk confusing readers by reducing the impact of effective and precise communication. Whereas some "tortured phrases" might represent simple mistranslations, in other cases, an abundance of such terms in a single preprint might reveal a more serious ethical issue, such as the undeclared use of a paper mill or an unprofessional editing service. This commentary is thus only a spring-board to introduce this linguistic phenomenon and to encourage interested academics to explore more cases, the practical implications of their existence, and even the weaknesses and strengths of PPS. Caution is needed about excessive extrapolation of the existence of "tortured phrases", so as not to automatically associate them with ethical infractions or misconduct.
