- Postgraduate course
- Arts and Humanities
- Cumulative final exam
What the course brings together
Language and its Applications treats language as a system that can be analysed at several connected levels.
- Assessment Homework and the term paper each contribute thirty per cent, while the final exam contributes forty per cent.
- Core method Describe the observable pattern before naming a linguistic category, rule or theory.
- Quantitative work Show probability or cosine steps and explain what the result does and does not represent.
- Date check Captured course files disagree on the final date, so confirm the operative schedule on Canvas.
How LT5903 is assessed
| Component | Weight | Format |
|---|---|---|
| Homework | 30% | Weekly group assignments across the teaching sequence |
| Term paper | 30% | A 2,000-word theoretical or empirical linguistics paper |
| Final exam | 40% | End-of-term assessment; detailed format and permitted materials are not stated in the captured files |
The detailed course schedule and introductory lecture publish the same component weights. Captured files disagree on whether the final is on 23 or 24 November, so confirm the operative date and format on Canvas. Attendance also carries a course-level pass condition: after more than 7 absences, students must contact the instructor, and failing to do so results in failing the course. This is an absence count, not a rule expressed as more weeks. Check the course Canvas page for the current operational record. The official catalogue lists the aggregate as continuous assessment.
What LT5903 covers
The guide follows the published sequence from language systems through sound, words, syntax and meaning to acquisition, the brain, social variation and computation.
Language Systems and Design Features
competence and performance, linguistic levels, design features and the communication chainLanguage as organised knowledge
This chapter separates a speaker's hidden linguistic competence from performance in production and comprehension.
- Competence against performance
- Levels of linguistic analysis
- The speech communication chain
- Arbitrariness and cultural transmission
- Discreteness, displacement and productivity
Speech Production and Perception
articulatory, acoustic and auditory phonetics, IPA, formants and speech perceptionThree views of one speech event
Articulatory phonetics describes the gesture, acoustic phonetics describes the signal and auditory phonetics describes perception.
- Articulatory, acoustic and auditory phonetics
- IPA consonant descriptions
- Vowel-space features
- Spectrogram axes and formants
- Competing accounts of speech perception
Sound Patterns and Phonological Rules
phonotactics, distributions, allophones, natural classes and conditioned processesDistribution before notation
Phonology studies how sounds are organised within a language. This chapter moves from phonotactic and sonority constraints to phoneme-allophone analysis.
- Phonotactics and sonority
- Minimal pairs and phonemes
- Complementary distribution and allophones
- Natural classes and feature rules
- Major phonological processes
Word Structure and Morphological Analysis
inflection, derivation, allomorphy, rule ordering, word formation and morphological treesWords have internal hierarchy
Morphology distinguishes open and closed categories, inflection from derivation, free roots from bound affixes and morphemes from their allomorphs.
- Lexical categories
- Inflection against derivation
- Morphemes and allomorphs
- Word-formation processes
- Hierarchical word trees
Constituency, Rules and Syntactic Ambiguity
arguments, adjuncts, word order, constituency tests, phrase rules and competing parsesEvidence for structure
Syntax asks how words and phrases combine. Co-occurrence distinguishes required arguments from optional adjuncts; word order and agreement constrain combinations.
- Arguments and adjuncts
- Word order and agreement
- Constituency tests
- Phrase-structure rules
- Structural ambiguity
Lexical Meaning and Semantic Relations
sense, reference, lexical relations, adjective classes, propositions and entailmentMeaning through relations and truth
Semantics separates sense from reference and uses set relations to organise lexical meaning. Hyponymy, synonymy and several types of antonymy behave differently.
- Sense and reference
- Hyponymy and synonymy
- Types of antonymy
- Adjective composition
- Truth conditions and entailment
Context, Cooperation and Implicature
utterances, context, felicity, conversational maxims, flouting and cancellationMeaning in an event
Pragmatics treats an utterance as a situated event with a speaker, hearer, time and place. Linguistic, situational and social context can change how the same words function. Felicity concerns appropriateness in that setting.
- Sentences and utterances
- Three kinds of context
- Felicity
- Conversational maxims
- Implicature and cancellation
How Children Acquire Language
acquisition theories, infant research methods, corpus evidence and word segmentationTheories need distinguishing predictions
Language acquisition is explained through innateness, imitation, reinforcement, active construction, connectionist learning and social interaction.
- Innateness and critical periods
- Imitation and reinforcement limits
- Active construction and connectionism
- Infant research paradigms
- Transitional probability and segmentation
Language in the Brain
aphasia, dual streams, neural signals and the trade-offs among imaging methodsMethods constrain neural claims
Psycholinguistics focuses on processing steps, while neurolinguistics focuses on their neural basis.
- Psycholinguistics and neurolinguistics
- Aphasia evidence
- Ventral and dorsal streams
- Haemodynamic measurement
- EEG, MEG and ECoG trade-offs
Language Variation and Computation
systematic varieties, social factors, parsing, distributional semantics and cosine similaritySystematic patterns in people and models
Sociolinguistics defines varieties through systematic structural or lexical features and separates linguistic organisation from social prestige.
- Dialect and language classification
- Standard prestige and systematicity
- Dimensions of social variation
- Context-free parsing
- Word vectors and cosine similarity
The foundation block moves from physical speech production and perception to language-specific sound patterns, the internal structure of words, phrase and sentence structure, conventional meaning and meaning inferred in conversation.
The application block then asks how children learn those systems, how linguistic processing is represented in the brain, how social structure and identity shape language variation, and how computational methods turn linguistic structure and contextual patterns into operations a machine can perform.
What strong answers have in common
The course repeatedly rewards diagnosis rather than label recall.
A phonological answer needs a distribution and conditioning environment. A morphological answer needs attachment order and category labels. A syntactic answer needs evidence for constituents and, where relevant, competing trees. A semantic answer needs truth conditions or set relations, while a pragmatic answer needs literal content, context and a cancellability test.
Experimental questions require a measured behaviour, the inference drawn from it and a limitation. Computational questions add explicit arithmetic, followed by an interpretation narrow enough to match the representation.
The attendance pass condition
Attendance carries a course-level pass consequence outside the weighted table.
After more than 7 absences, a student must contact the instructor to discuss the situation; failing to make that contact results in failing the course. This is an absence count, not a rule expressed as more weeks.
Check the course Canvas page for the current operational record and any updates.
How to revise across topics
Build a single evidence ledger with four columns: observation, classification, mechanism and alternative. Fill it with one new case from every chapter. This makes the shared reasoning visible without collapsing the subject areas into one vocabulary.
Finish by practising short explanations because the captured assignment asks for concise answers, then extend selected cases into fuller arguments suitable for the term paper and cumulative final.

LT5903 FAQ
How is the course assessed?
Homework contributes thirty per cent, the term paper contributes thirty per cent and the final exam contributes forty per cent. The official catalogue displays the aggregate as continuous assessment, while the detailed schedule provides the component split. Attendance and late-day rules can also change the overall course grade, so treat them as course-level conditions.
When is the final and what is its format?
Two captured CityU files disagree on whether the final occurs on 23 or 24 November. One lecture slide gives an evening time window, but the detailed sections, question count and permitted materials are not published in the captured set. Confirm the operative date, venue, format and aids on the course Canvas page.
Does the guide contain a past paper?
No past final, practice final, sample paper or final solution appears in the captured course folder. The practice questions in this guide are newly authored from the analytic operations demonstrated in lectures, including distributional diagnosis, tree building, inference tests, method comparison and vector calculations. They should not be read as predictions of an unpublished format.
How should I start a phonology problem?
Begin with distribution. Ask whether the sounds share an environment, whether exchanging them changes meaning and whether the environment predicts their occurrence. Only then decide between contrastive distribution, complementary distribution and free variation. A feature rule comes last because it summarises a supported pattern; it cannot substitute for the diagnosis.
What makes a syntactic analysis convincing?
Use more than one constituency test where possible, identify required arguments before optional adjuncts and write the phrase-structure rules that license the tree. For an ambiguous string, draw both structures and point to the different attachment site. Paraphrases are useful for displaying the readings, but the trees explain why both readings exist.
How do entailment and implicature differ?
Entailment follows from truth conditions and cannot be cancelled without contradiction. Implicature is inferred from context and expectations about cooperative conversation, so it may be cancelled. In an answer, state literal content first, name the conversational maxim that motivates the inference and then write an explicit cancellation clause as the diagnostic.
Is there mathematics in the course?
Yes. The computational linguistics material assigns probabilities to word-context pairs and works through cosine similarity, while language acquisition uses transitional probability as a segmentation cue. Phonetics and neurolinguistics also require interpreting measured frequencies, timing and spatial resolution. Show each numerical step and finish with a linguistic interpretation.
Where are marks most often lost?
The captured files do not provide a marking guide, so this guide does not invent one. The safest practical focus is completeness of analysis: name the observation, apply the correct diagnostic, show the rule or calculation, consider an alternative and limit the conclusion. A correct label with no supporting evidence is much harder to evaluate than a transparent chain of reasoning.
What attendance condition can affect passing?
Attendance carries a course-level pass condition outside the weighted table. After more than 7 absences, a student must contact the instructor to discuss the situation; failing to contact the instructor results in failing the course. This is an absence count, not a rule expressed as more weeks. Check the course Canvas page for the current operational record and any updates.
Questions students ask in each LT5903 chapter
- Why can a speech error be poor evidence about grammar?
- Production is affected by memory, attention and planning, so an observable error may arise during performance while the underlying linguistic knowledge remains intact. Use grammatical judgements and recurring systematic patterns alongside the error before making a claim about competence. Chapter 01 · Language Systems and Design Features
- Why is ordinary spelling unreliable for phonetic analysis?
- One spelling can represent different sounds and one sound can be represented by different spellings. IPA supplies a more stable sound-symbol relation, letting an answer describe what was produced rather than what letters happen to appear in the word. Chapter 02 · Speech Production and Perception
- What proves that two sounds are separate phonemes?
- A minimal pair is strong evidence because the sounds occur in the same environment and changing one changes meaning. If the environments never overlap, examine whether context predicts their distribution before claiming a contrast. Chapter 03 · Sound Patterns and Phonological Rules
- How can I distinguish inflection from derivation?
- Check whether the operation creates a new lexeme and whether it changes lexical category. Inflection normally expresses grammatical information while keeping the lexeme and category; derivation creates a new lexical item and frequently changes category. Chapter 04 · Word Structure and Morphological Analysis
- Why should I use several constituency tests?
- Question answers, clefting and pro-form substitution each have limitations. Converging results provide stronger evidence, while a failed cleft alone may reflect restrictions on that construction rather than absence of a constituent. Chapter 05 · Constituency, Rules and Syntactic Ambiguity
- Can an expression have sense without reference?
- Yes. A conventional concept may be understood even when no actual entity satisfies it. This is why reference cannot exhaust meaning and why two expressions can share a referent while presenting that entity through different senses. Chapter 06 · Lexical Meaning and Semantic Relations
- What does context add to sentence meaning?
- Linguistic context supplies prior discourse, situational context supplies facts about the setting and social context supplies participant relationships. Together they can turn an ability question into a request or make an otherwise ordinary response inappropriate. Chapter 07 · Context, Cooperation and Implicature
- Why is imitation insufficient as a complete theory?
- Children produce novel sentences and systematic forms that adults do not provide, so direct copying cannot explain the whole pattern. Imitation may contribute input, but a learning account must explain productive generalisation beyond heard examples. Chapter 08 · How Children Acquire Language
- Why is fMRI called an indirect measure?
- It measures blood oxygenation changes associated with neural activity rather than electrical firing itself. The haemodynamic response is delayed and reflects population activity, so timing claims must respect that measurement chain. Chapter 09 · Language in the Brain
- Does nonstandard mean unsystematic?
- No. A nonstandard variety can have stable phonological, morphological and syntactic rules. Standard status reflects institutional prestige and social power, not greater linguistic logic. Analyse the pattern before evaluating its social meaning. Chapter 10 · Language Variation and Computation
How to study for the exam
Work in three passes. First, build paired distinctions and retrieve both sides without notes. Second, solve one unfamiliar data problem per chapter, writing the observation before the label and the diagnostic before the conclusion.
Third, interleave topics: compare phonological and morphological rule ordering, syntactic and semantic composition, semantic entailment and pragmatic inference, infant and neural methods, and human variation with computational representation. Keep a correction log organised by error type rather than lecture. For calculations, preserve the raw values, every operation and the interpretation.
For trees and rules, preserve category labels and conditioning environments. In the final week, practise concise responses because the captured assignment uses short answers, but do not assume that its format is the final format. Confirm the final date, venue, sections and permitted materials on Canvas because the captured schedule and introductory lecture disagree on the day and do not publish the remaining format details.
