L1 Typological Distance and Arabic L2 Writing Development in a Multinational Saudi University Program: A Cross-Level Learner-Corpus Study

Learning a new language is often described as building a bridge from what you already know to something entirely new. For most people, the starting point is their native tongue, the language they have spoken since childhood. But when that native language is very different from the one they are trying to learn, the journey becomes significantly harder. This is especially true for Arabic, a language with a unique script that flows from right to left, a complex system of word formation based on roots, and strict rules about how words must agree with one another in gender and number. For decades, researchers have wondered how much a learner's first language helps or hinders their progress in writing Arabic. While we know that some learners pick up the script and grammar faster than others, it has been difficult to prove exactly why, because many studies simply group students by their nationality rather than looking closely at the specific linguistic tools they bring with them.

A team of researchers at the University of Ha'il in Saudi Arabia decided to look past simple labels like "nationality" to find the real story behind these differences. They focused on a concept called "typological distance," which is a way of measuring how structurally similar or different two languages are. Imagine two languages as two different types of machinery; if they share many of the same gears and levers, they are close together. If one uses gears and the other uses pulleys, they are far apart. The researchers wanted to see if this distance predicted how well students could write in Arabic. They gathered a group of 27 students from a wide variety of backgrounds, including learners from West Africa, South Asia, East Asia, and Europe, all enrolled in the same university program. Crucially, they did not just assume these students' first languages based on their passports. Instead, they asked each student to verify their actual native language, their literacy in other scripts, and their previous exposure to Arabic. This careful verification allowed the team to sort the students into three groups: those whose native languages were very close to Arabic, those who were moderately different, and those who were very distant.

The researchers then asked these students to write two types of texts. One was a controlled task where they had to produce specific sentences under strict conditions, designed to test their grasp of spelling and grammar rules. The other was a free-writing task where they could express themselves on a general topic, allowing the researchers to see how they organized their thoughts and used common phrases. By analyzing these writings, the team looked for specific patterns: how many spelling mistakes were made, how often grammar rules were broken, how many natural-sounding word groups were used, and how complex the sentences were. They found a clear and consistent pattern that followed the distance between the languages. Students whose native languages were structurally close to Arabic made far fewer mistakes in spelling and grammar. They also used more natural, fluent phrases and built more complex sentences. In contrast, students from the most distant language backgrounds struggled significantly more with the basic mechanics of writing, such as placing dots correctly on letters or matching adjectives to nouns, and they used fewer of those smooth, ready-made phrases that make writing sound professional.

The study also revealed that while getting better at the language helped everyone, it did not erase the initial gap. The researchers compared students at two different levels of the program, a lower level and a higher level. As expected, the students at the higher level performed better overall than those at the lower level. They made fewer errors and used more sophisticated language. However, even at the higher level, the students from distant language backgrounds still lagged behind their peers from closer backgrounds. The gap in basic accuracy narrowed, but the difference in how fluently and complexly they wrote remained visible. For example, a student from a language very close to Arabic at the higher level used nearly three times as many natural word groups as a student from a very distant language at the same level. This suggests that while instruction can fix surface-level errors, the deep structural differences between languages continue to influence how a person constructs complex thoughts in writing.

The researchers also examined the specific types of mistakes made by the different groups. Students from distant backgrounds frequently confused the gender of nouns or used the wrong pronouns, errors that stem from their native languages not having these same rules. One student, for instance, wrote a sentence where the adjective did not match the gender of the noun it described, a mistake that would not occur if their native language had similar agreement rules. On the other hand, students from closer backgrounds were able to use standard academic phrases that native speakers use naturally, showing that their prior linguistic knowledge gave them a head start in mastering the flow of the language. The study did not claim to have solved the entire puzzle of language learning, nor did it say that distance is the only factor that matters. It did, however, provide strong evidence that the structural similarity between a learner's first language and Arabic is a powerful predictor of their writing development.

This work matters because it moves beyond general assumptions about who learns Arabic well and looks at the specific mechanics of why. By verifying the actual languages students speak and measuring the specific distance between those languages and Arabic, the researchers showed that language learning is not a one-size-fits-all process. The findings suggest that teachers in multilingual classrooms might need to offer different kinds of support depending on where their students are coming from. Students from very distant language backgrounds may need extra help with the basic building blocks of the script and grammar, while those from closer backgrounds might benefit more from instruction focused on fluency and complex expression. The study concludes that understanding the specific linguistic bridge a student is building is essential for helping them cross it successfully.
