News headlines like other pieces of writings use rhetorical devices. They are regarded as the initial informative and persuasive part of news stories. The goal of the present study was to analyze COVID-19-related native and non-native news headlines chosen from two main online news websites in Iran and England in terms of number and degree of utilization of sub-types of rhetorical devices. To this end, the 6-week corpus including 489 headlines relevant to corona-virus news (282 headlines selected from the BBC and 207 from the Tehran Times) were analyzed. Shams (2013) and Picello (2018) taxonomies were used to analyze all news headlines. The findings showed that ten rhetorical devices were found in these headlines. Alliteration was used most frequently, following closely behind were metonymy, rhyme, rhetorical question, depersonalization, hyperbole, metaphor, pun, cliché, and euphemism. Both alliteration and metonymy were frequently used in the headlines of the news stories. However, just simile and allusion were found in the Tehran Times headlines, but not with high frequency. The findings can provide insights into the understanding of rhetoric-specific conventions in news headlines for ELT teachers and students. Also, English teachers can use news headlines as authentic teaching materials in their language classrooms.
