For example, in our on a number of interrelated factors. A difference between ‘jump’ and its past tense work on how Turkish speakers treat English consideration of the relationship between form, ‘jumped’, instead using the uninflected articles, we have found that some learners different grammatical components, such as form in past tense contexts (in other words, resort to stressing articles because it allows phonology, morphology and syntax, may help omitting the inflection). them to analyse articles in terms of their explain both the successes and the difficulties L1 prosodic representations.
