Unit 6: Vocabulary

I. Orientation: Vocabulary as a System of Meaning

Vocabulary is the organized body of words and multiword expressions used to communicate meaning. Effective vocabulary knowledge includes not only knowing definitions, but also recognizing relationships between words, grammatical patterns, contextual meanings, connotations, and figurative uses.

• Form: A lexical item has a spoken and written form, such as communicate, /kəˈmjuːnɪkeɪt/, and may change through inflection: communicates, communicated, communicating.
• Meaning: Words carry denotative meaning, or dictionary meaning, and connotative meaning, or associated feeling; slim and skinny both suggest thinness but differ in connotation.
• Use: Appropriate vocabulary depends on context, purpose, audience, register, and subject; request assistance is formal, while ask for help is neutral.
• Relationship: Words form networks through similarity, opposition, sound, spelling, and association, as in synonyms, antonyms, homophones, and collocations.
• Combination: Words follow conventional patterns; English speakers normally say make a decision, not do a decision.
• Context: Surrounding words and situations help determine intended meaning; bank refers to a financial institution in “deposit money in the bank” but to land in “the river bank.”
• Productive control: Active vocabulary enables accurate speaking and writing, whereas receptive vocabulary supports understanding during reading and listening.

II. Lexical Relationships: Similarity and Opposition

A. synonyms and antonyms

Synonyms express similar meanings, whereas antonyms express contrasting meanings, but their use depends on context, degree, and register.

1. Synonyms

   • Definition: Synonyms are words with identical or closely related meanings, such as begin/start, rapid/quick, and purchase/buy.
   • Partial equivalence: Most synonyms are not interchangeable in every context; strong tea is natural, but powerful tea is not.
   • Register: Synonyms may differ in formality:
     • ask is neutral.
     • inquire is formal.
     • question may imply doubt or interrogation.
   • Connotation: Confident suggests justified self-belief, while arrogant conveys excessive pride.
   • Precision: Choosing among walk, stroll, march, and wander communicates different manners and purposes of movement.

2. Antonyms

   • Gradable antonyms: Opposites lie on a scale, as with hot/cold; intermediate states include warm and cool.
   • Complementary antonyms: One term excludes the other, as in alive/dead and legal/illegal.
   • Relational antonyms: Each word describes the same relationship from an opposite viewpoint, as in buy/sell, lend/borrow, and employer/employee.
   • Contextual opposition: The opposite of old may be young for a person but new for an object.

III. Multiword Vocabulary: Conventional Word Combinations

A. phrasal verbs

A phrasal verb combines a verb with one or more particles to create a meaning that may differ from the meaning of the individual words.

• Structure: Common patterns include verb + adverb (give up), verb + preposition (look after), and verb + adverb + preposition (put up with).
• Idiomatic meaning: Carry on means “continue,” while turn down may mean “reject” rather than physically rotate something.
• Separable forms: An object may occur between the verb and particle: “Turn the radio down” or “Turn down the radio.” A pronoun must intervene: “Turn it down.”
• Inseparable forms: The object follows the complete unit: “She looks after her grandmother,” not “looks her grandmother after.”
• Transitivity: Bring up requires an object in “She brought up the issue,” whereas show up can stand alone in “He did not show up.”
• Polysemy: One phrasal verb may have several meanings:
  • take off an item means remove it.
  • An aircraft takes off when it leaves the ground.
  • A business takes off when it becomes successful.
• Register: Phrasal verbs are frequent in conversation; formal alternatives include postpone for put off and investigate for look into.

B. verb phrases

A verb phrase consists of a main verb together with auxiliaries, complements, or particles that express an action, state, time, aspect, voice, or modality.

• Main verb: In “They completed the report,” completed carries the central lexical meaning.
• Auxiliaries: Primary auxiliaries be, have, and do form grammatical constructions: “She has finished” and “They are waiting.”
• Modal verbs: Can, could, may, might, must, shall, should, will, and would express possibility, ability, obligation, or prediction: “You must submit the form.”
• Tense and aspect: “She has been working” combines present tense, perfect aspect, and progressive aspect.
• Voice: “The team completed the project” is active; “The project was completed by the team” is passive.
• Complementation: Different verbs require different patterns:
  • enjoy takes an -ing form: “enjoy reading.”
  • decide takes a to-infinitive: “decide to leave.”
  • give can take two objects: “give the client an update.”
• Agreement: The finite verb agrees with its subject: “The list is complete,” but “The items are complete.”

C. compound nouns

A compound noun combines two or more words to name a person, object, place, activity, or idea as a single lexical unit.

• Forms: Compounds may be closed (website), hyphenated (check-in), or open (credit card); established dictionary usage determines spelling.
• Stress: Spoken compounds often stress the first element; a GREENhouse is a glass structure, while a green HOUSE is a house painted green.
• Head word: The final element usually identifies the category; a coffee cup is a type of cup, while a cup holder is a type of holder.
• Plural formation: The main element normally becomes plural: toothbrushes and credit cards. In compounds such as mothers-in-law, the central noun takes the plural.
• Meaning relationship: The first element may indicate purpose (washing machine), material (stone wall), location (office chair), or content (water bottle).
• Distinction from phrases: A compound represents an established concept, whereas an ordinary noun phrase gives a temporary description; blackboard names an object that need not be black.

D. idiomatic collocations

Idiomatic collocations are conventional combinations whose word choices are restricted by established usage rather than grammar alone.

• Collocation principle: Speakers say heavy rain, strong argument, and deep concern because these combinations have become conventional.
• Common patterns: Frequent structures include adjective + noun (major problem), verb + noun (reach an agreement), noun + noun (market research), and adverb + adjective (highly effective).
• Restricted choice: Commit a crime is conventional, while perform a crime is grammatically possible but unnatural.
• Idiomatic force: Some combinations are partly figurative; break the news means announce important information, not physically break anything.
• Register and domain: Academic English favors combinations such as conduct research, draw a conclusion, and provide evidence.
• Natural production: Learning a word with its partners is more useful than learning it alone; responsible should be associated with responsible for, and depend with depend on.
• Variation: Collocations may permit limited substitution, as in pose/present/create a problem, but each verb adds a slightly different emphasis.

IV. Meaning in Communication: Context and Change

A. vocabulary in context

Vocabulary in context involves determining and selecting meaning through surrounding language, situation, register, tone, and communicative purpose.

• Co-text: Nearby words clarify meaning; in “The crane lifted the steel beam,” lifted and steel beam identify crane as a machine.
• Situational context: “That is cold” may describe temperature, food, weather, or emotionally insensitive behavior.
• Grammatical clues: Position reveals word class; record is a noun in “a written record” but a verb in “record the meeting.”
• Semantic clues: Definitions, examples, contrasts, and cause-effect relations help interpretation; “Unlike his gregarious sister, Amir was reserved” contrasts gregarious with reserved.
• Register: Children, kids, and minors refer to similar groups but suit neutral, informal, and legal contexts respectively.
• Tone and connotation: “A persistent employee” is generally positive, while “a stubborn employee” is critical.
• Selection strategy: The reader should test a possible meaning against the entire sentence rather than rely on one neighboring word.

B. describing trends

Describing trends requires precise vocabulary for direction, degree, speed, fluctuation, and time.

• Upward movement: Verbs include rise, increase, grow, climb, and surge; nouns include a rise, an increase, and growth.
• Downward movement: Fall, decline, decrease, drop, and plunge indicate reduction, with plunge suggesting a large, rapid fall.
• Stability: Remain stable, level off, stabilize, and plateau describe little change or the end of movement.
• Fluctuation: Fluctuate describes repeated rises and falls; “Prices fluctuated between ₹80 and ₹95.”
• Degree: Adverbs such as slightly, steadily, considerably, sharply, and dramatically quantify manner and intensity.
• Numerical accuracy: “Sales rose by 20%” states the amount of change; “sales rose to 120 units” states the final value.
• Time reference: Expressions such as between 2020 and 2024, during the first quarter, and over five years establish the period.
• Objective style: Trend descriptions should report evidence without unsupported causes: “Output declined sharply in June” is factual; the reason requires separate evidence.

V. Form and Meaning: Lexical Ambiguity

A. homonyms

Homonyms are words that share the same spelling or pronunciation but have unrelated meanings.

• Core feature: The meanings are historically or semantically distinct; bank can mean a financial institution or the side of a river.
• Grammatical variation: Bear may be a noun naming an animal or a verb meaning tolerate: “I cannot bear the noise.”
• Contextual resolution: “She opened an account at the bank” and “They sat on the bank” provide enough semantic information to distinguish meanings.
• Dictionary treatment: Unrelated meanings may appear as separate entries, unlike related senses of one polysemous word.
• Communication risk: Ambiguity occurs when context is insufficient, as in “He went to the bank.”

B. homophones

Homophones are words with the same pronunciation but different meanings and usually different spellings.

• Examples: Right/write, sea/see, principal/principle, and stationary/stationery are distinguished in writing but not in speech.
• Meaning contrast: A principal may be a school head or main amount of money; a principle is a rule or belief.
• Spelling control: Grammar helps distinguish their (possessive), there (place), and they’re (“they are”).
• Listening dependence: In speech, surrounding meaning resolves the choice: “Please write your name” cannot logically use right.
• Professional accuracy: Homophone errors can alter meaning and reduce credibility in formal documents.

C. homographs

Homographs are words with identical spellings but different meanings and, in some cases, different pronunciations.

• Same pronunciation: Bat may mean a flying mammal or a piece of sporting equipment.
• Different pronunciation: Lead /liːd/ means guide, while lead /led/ names a metal.
• Stress change: Record is commonly pronounced REcord as a noun and reCORD as a verb.
• Context and syntax: “They will present the award” uses a verb, while “She received a present” uses a noun.
• Reading significance: Correct pronunciation depends on identifying meaning and grammatical function before speaking.

VI. Figurative Expression: Meaning Beyond the Literal

A. metaphorical language

Metaphorical language explains or intensifies one idea by describing it in terms of another, creating a non-literal relationship between domains.

• Metaphor: “Time is money” maps the limited, valuable quality of money onto time; people therefore spend, save, or waste time.
• Implied comparison: Unlike a simile, a metaphor does not normally use like or as; “Her voice was velvet” suggests softness without literal identification.
• Conceptual pattern: Expressions such as defend an argument, attack a claim, and win a debate reflect the conceptual metaphor ARGUMENT IS WAR.
• Personification: Human qualities are assigned to non-human entities, as in “Opportunity knocked” or “The evidence speaks for itself.”
• Dead metaphor: Familiar expressions such as the foot of a mountain or the branch of a company may no longer feel strongly figurative.
• Purpose: Metaphors make abstract ideas concrete, compress complex meaning, establish tone, and strengthen persuasion.
• Interpretation: Meaning depends on shared associations; “The project is on the rocks” suggests serious difficulty, not a literal physical position.
• Control and clarity: Mixed metaphors weaken communication; combining “We must get the ball rolling” with “before the ship leaves the station” creates incompatible images.
