1. Introduction & Overview
This research paper, published in the Quarterly Journal of Language and Dialect Studies of Western Iran, investigates the lexical errors produced by Kurdish-Farsi bilinguals residing in Kermanshah when speaking standard Farsi. The study is grounded in the understanding that errors are systematic deviations arising from violations of second language (L2) rules. Its primary objectives are to identify the sources (interlingual vs. intralingual) and analyze the distribution patterns of these lexical errors within the spoken discourse of this specific bilingual population.
The significance of this work lies in its potential to inform language teaching methodologies, assessment design, and the development of bilingual educational resources, ultimately aiming to facilitate smoother communication between Kurdish speakers and Farsi speakers.
2. Research Methodology
The study employs a mixed-methods (quantitative-qualitative) descriptive approach.
2.1 Participants & Sampling
The target population consisted of first-grade junior high school students (aged 13-15) in Kermanshah who are bilingual in Kurdish (Kolyai dialect) and Farsi. A sample of 190 students (95 girls, 95 boys) was selected using voluntary response sampling. All participants learned Farsi as a second language upon entering school.
2.2 Data Collection & Procedure
Data was collected through interview sessions with 4-5 participants per session. Participants were asked to narrate a personal memory in Farsi. Each interview lasted 4-5 minutes on average, with no time constraints. Responses were recorded and transcribed for analysis.
2.3 Analytical Framework
The core analytical framework for error classification is the taxonomy proposed by Dulay, Burt, and Krashen (1982). Errors are categorized into three main types:
- Interlingual Errors: Caused by interference from the native language (Kurdish).
- Intralingual Errors: Caused by faulty or incomplete learning of the target language (Farsi) itself.
- Developmental Errors: Errors that resemble those made by children acquiring their first language.
3. Results & Findings
3.1 Error Classification & Frequency
The analysis of transcribed speech revealed that the observed lexical errors had both intralingual and interlingual origins. The collected errors were systematically classified according to the Dulay et al. framework.
3.2 Distribution of Error Types
The results indicated that the most frequently occurring errors were, in order:
- Interlingual Errors (Highest frequency)
- Intralingual Errors
This distribution suggests that native language (Kurdish) interference is a predominant source of lexical difficulty for Kolyai Kurdish speakers learning Farsi, followed by challenges internal to the structure and learning of Farsi itself.
4. Discussion & Implications
The findings provide a descriptive account of lexical challenges faced by Kolyai Kurdish-Farsi bilinguals and lead to several key implications.
4.1 Pedagogical Implications
The prevalence of interlingual errors underscores the need for teaching methods that explicitly address cross-linguistic differences between Kurdish and Farsi. Contrastive analysis can be a valuable tool for teachers to anticipate and remediate these specific error types.
4.2 Material & Curriculum Development
The study strongly emphasizes the necessity of reforming teaching methods, test designs, and curricular resources. It advocates for the development of targeted bilingual textbooks and materials that bridge the specific lexical gaps identified, thereby supporting more effective Farsi acquisition for Kurdish-speaking students.
5. Technical Analysis & Framework
The study's core analysis can be framed as a classification problem. Let $E$ represent the set of all lexical errors identified. The function $f(e)$ classifies each error $e \in E$ into a category $C$ based on its hypothesized source:
$f(e) \rightarrow C \in \{C_{inter}, C_{intra}, C_{dev}\}$
Where:
$C_{inter}$ = Interlingual Error (Kurdish interference)
$C_{intra}$ = Intralingual Error (Farsi-internal)
$C_{dev}$ = Developmental Error
The research then calculates the frequency distribution $P(C)$ for the sample:
$P(C) = \frac{N(C)}{N(E)}$, where $N(C)$ is the count of errors in category $C$, and $N(E)$ is the total number of errors.
The finding that $P(C_{inter}) > P(C_{intra})$ is the key quantitative result, pointing to L1 transfer as the major contributing factor.
6. Experimental Results & Charts
Chart Description (Hypothetical based on findings): A bar chart titled "Distribution of Lexical Error Types in Kurdish-Farsi Bilingual Speech." The x-axis lists the three error categories: "Interlingual," "Intralingual," and "Developmental." The y-axis represents the percentage frequency of occurrence (%). The "Interlingual" bar is the tallest, representing approximately 60-70% of total errors. The "Intralingual" bar is shorter, representing approximately 25-35%. The "Developmental" bar is the shortest or potentially absent, representing a minimal percentage. This visualization clearly demonstrates the dominance of cross-linguistic transfer errors in the dataset.
7. Analytical Framework: Case Example
Scenario: A Kurdish-Farsi bilingual student says, "*من آن کتاب را دستم" (Man ān ketāb rā dastam), intending to say "I took that book." The correct Farsi verb is "گرفتم" (gereftam). The Kurdish verb for "to take" is "دەست پێکردن" (dest pê kirdin), which literally involves the root "دەست" (dest - hand).
Analysis using Dulay et al. Framework:
- Error: Using "دستم" (my hand) as a verb.
- Classification: Interlingual Error.
- Source: Direct lexical transfer and calque from Kurdish, where the concept of "taking" is lexically linked to "hand." The student incorrectly maps the Kurdish conceptual-lexical unit onto Farsi.
8. Future Applications & Research Directions
- Computational Modeling: The error taxonomy and frequency data can be used to train AI models for automatic error detection in the speech/writing of Kurdish-Farsi learners, similar to Grammarly but for specific bilingual pairs.
- Adaptive Learning Platforms: Develop digital tutoring systems that predict a learner's likely error types based on their L1 (Kurdish dialect) and provide personalized exercises targeting interlingual transfers.
- Neurolinguistic Research: Use fMRI or EEG to study the brain activity associated with producing interlingual vs. intralingual errors, providing a biological correlate to the behavioral classification.
- Longitudinal Studies: Track the same bilingual individuals over time to see how the ratio of interlingual to intralingual errors changes with increasing proficiency, testing the tenets of the Krashen's Natural Order Hypothesis in a bilingual context.
- Expansion to Other Dialects/Languages: Replicate the study with other Kurdish dialects (Sorani, Kurmanji) and other L1 backgrounds in Iran (e.g., Turkish, Arabic) to create a comparative map of lexical challenge profiles for Farsi learners.

Analyst Insight: A Critical Deconstruction
Core Insight: This study delivers a crucial, yet narrowly focused, validation of a classic theory. Its primary value isn't in discovering something new about language acquisition broadly, but in providing empirical, localized evidence that for Kolyai Kurdish speakers, the mother tongue is the primary architect of lexical error in Farsi. This isn't just an academic point; it's a direct challenge to one-size-fits-all Farsi teaching methodologies in multilingual Iran.
Logical Flow & Strengths: The research logic is sound and replicable. By anchoring itself in the established Dulay-Burt-Krashen taxonomy, it gains immediate credibility and allows for cross-study comparison—a strength often missing in isolated regional studies. The mixed-methods approach (qualitative error classification backed by quantitative frequency counts) is appropriate. Its greatest strength is its actionable specificity: it doesn't just say "errors happen"; it identifies the predominant type and points to the specific language pair as the source.
Flaws & Critical Gaps: The methodology is its own limitation. Relying on a single, open-ended narrative task may not elicit the full range of lexical errors, especially those tied to specific, less personal vocabulary domains. The voluntary sampling risks a self-selection bias—perhaps more confident or willing students participated. Most critically, the study stops at classification and frequency. It doesn't delve into the cognitive mechanisms behind the interlingual transfers. Are they due to direct word-for-word translation, conceptual mapping differences, or gaps in mental lexicon? As Selinker's (1972) interlanguage theory suggests, these errors are windows into the learner's unique linguistic system, but this study merely labels the window without describing the view inside.
Actionable Insights: For educators and policymakers, this research is a mandate for contrastive pedagogy. Curriculum designers must move beyond generic Farsi textbooks and develop materials that preemptively address known Kurdish-to-Farsi lexical traps. For researchers, the path forward is clear: 1) Deepen the cognitive analysis using think-aloud protocols to uncover the "why" behind the errors. 2) Embrace technology—build a corpus of these errors to train predictive models, creating tools that offer real-time, targeted feedback. 3) Expand the scope to syntactic and phonological errors to build a complete profile. In essence, this paper is a solid foundation. The next step is to build a more sophisticated structure upon it that not only diagnoses the problem but also engineers the solution based on a deeper understanding of the bilingual mind.
