Abstract Despite the importance of mastering different types of formulaic sequences in a second language, little is known about the relative effect of different input modes on their acquisition. This study explores the learning of a particular type of formulaic language (binomials) in three input modes (reading-only, listening-only, and reading-while-listening) at different frequencies of exposure (2, 4, 5 and 6 occurrences). Arabic learners of English were presented with three stories, each in a different mode, that contained novel binomials (e.g., wires and pipes ) and existing binomials (e.g., brother and sister ). Two post-tests (multiple-choice and familiarity ratings) assessed learners’ knowledge of the binomials. Results showed that reading-only and reading-while-listening led to better performance on the tasks than listening-only. Frequency of exposure had an effect on the perceived familiarity of binomials.
