Language and Linguistics
This domain tests your grasp of the language systems ELLs must learn-phonology, morphology, syntax, semantics, and pragmatics-plus the major theories of first- and second-language acquisition and how they explain learner errors and instructional choices.
Core concepts
- Phonology is the sound system; a phoneme is a contrastive sound unit (/b/ vs. /p/), while phonemic awareness is the ability to hear and manipulate those units. Phonics is the mapping of sounds to letters-not the same thing.
- Morphology studies morphemes: free (book) and bound (-s, un-). Syntax covers word order and sentence structure; semantics covers meaning; pragmatics covers social use, such as politeness and register.
- Krashen: acquisition vs. learning, monitor, natural order, comprehensible input (i+1), affective filter.
- Cummins: BICS (conversational, context-embedded) versus CALP (academic, context-reduced). BICS can develop in 1–3 years; CALP often takes 5–7 years.
- Interlanguage is the learner's evolving rule system; errors may show transfer from L1, overgeneralization, or fossilization if feedback is absent.
- Vygotsky's ZPD and scaffolding explain how mediation supports growth; Chomsky's LAD is a nativist account, not a complete explanation of SLA.
Worked example
A student says, “She goed to the store yesterday.” The error is not evidence of low intelligence or L1 interference; it shows overgeneralization of the regular past-tense rule within the learner's interlanguage. The instructional response is to contrast irregular forms (went, saw, bought) in meaningful contexts and provide corrective recasts-not to drill every past-tense verb or assume the student needs phonics. Reasoning: the error is developmental and rule-governed; targeted, contextual feedback is more effective than broad remediation.
Traps that cost marks
- Treating BICS as sufficient for academic success; the exam often asks why an ELL who chats easily still struggles with textbook text.
- Labeling every error “L1 interference” when overgeneralization or developmental sequence is the better explanation.
- Confusing phonemic awareness with phonics, or morphology with syntax.
- Assuming older learners cannot acquire native-like pronunciation; the critical-period idea is nuanced, not absolute.
