Subtest I - Language, Linguistics, and Language Development
Subtest I: Language, Linguistics, and Language Development tests the formal linguistic knowledge that underpins English language development: phonology, morphology, syntax, semantics, pragmatics, first- and second-language acquisition, and the role of the primary language. Items ask you to analyze language data and apply acquisition theory, not to offer generic teaching tips.
Language structure
- Phonology: Phonemes are contrastive sounds. Minimal pairs such as pat/bat prove that /p/ and /b/ are separate English phonemes. Allophones are predictable variants of one phoneme. English syllable structure and first-language transfer shape pronunciation.
- Morphology: Free morphemes can stand alone; bound morphemes cannot. Inflectional suffixes add grammatical information without changing category (English plural -s, possessive -'s, third-person -s, past -ed, past participle -en, progressive -ing, comparative -er, superlative -est). Derivational affixes change meaning or word class.
- Syntax: Constituency tests include substitution, movement, and coordination. English is basically SVO, with noun, verb, prepositional, and complementizer phrases. Embedded clauses and question formation involve movement.
- Semantics and pragmatics: Semantics studies literal meaning and lexical relations (synonymy, antonymy, hyponymy, homonymy versus polysemy). Pragmatics studies speaker meaning: speech acts, implicature, politeness, and register.
Acquisition theory
Behaviorism stresses imitation and reinforcement; nativism proposes Universal Grammar and a language acquisition device; interactionism emphasizes social input and negotiation. In second language acquisition, know Krashen's comprehensible input and affective filter, Cummins's BICS/CALP distinction, interlanguage, positive and negative transfer, and fossilization. A well-developed primary language supports English through transfer and metalinguistic awareness.
Worked example
Analyze unbelievably. un- is a bound derivational prefix meaning 'not'; believe is a free root verb; -able is a bound derivational suffix changing verb to adjective ('able to be believed'); -ly is a bound derivational suffix changing adjective to adverb. The word has four morphemes, three of them bound. Reasoning: first test whether each piece can stand alone; then ask whether it changes category (derivational) or only adds grammatical information (inflectional).
Traps
Do not confuse phonemes with letters. Do not label every affix inflectional. Do not treat BICS as sufficient for academic CALP. Do not assume first-language influence is always interference. Do not collapse semantics into pragmatics.
