Research article (RA) titles are one of the most important elements of a manuscript, influencing the reviewers’ decision and editors’ judgment, attracting the readers, and conveying the main idea of the article. Investigating 3197 RA titles published in 16 approved Iranian linguistic journals, this study aimed to map their pattern and portray their features of form and content. To this end, all the RA titles of the 16 Iranian journals publishing articles in applied linguistics up to 2022 (3197 titles) were collected. Then, they were analyzed for their length, presence of non-alphanumeric characters, syntactic structure, lexical diversity, as well as type and trend of information encoded. Results show that RA titles in Iranian linguistic journals tend to be pretty long (average of 13.88) but mostly consist of non-repetitive words with high lexical diversity (.94). Authors mainly used colons (average of 82), hyphens (average of 79), and commas (average of 37) to form titles by nominal (average of 94) and compound (average of 82) grammatical structures. These titles mostly tended to embed information about the method, data, and results of the works and appeared to be highly informative. Interrelationships between features resulted in a checklist for RA title features that can be used by prospective researchers, academic writing instructors, and reviewers.
