Unit 6: Vocabulary

I. Orientation: Vocabulary as a System of Meaning and Use

Vocabulary is the organized knowledge of words, word combinations, meanings, pronunciation patterns, and figurative expressions used in communication. At the upper-intermediate level, vocabulary learning involves not only knowing definitions but also selecting words that suit a particular context, grammatical structure, register, and intended meaning.

• Form: A word has a written form, such as accept, and a spoken form, represented phonemically as /əkˈsept/.
• Meaning: Words may carry denotative meaning, or literal dictionary meaning, and connotative meaning, or associated emotional and cultural meaning.
• Function: A word performs a grammatical role, such as noun, verb, adjective, or adverb: decision, decide, decisive, and decisively.
• Context: Surrounding words and situations determine intended meaning; issue can mean a topic, a problem, or the act of officially providing something.
• Collocation: Words regularly occur in conventional combinations, such as make a decision and deeply concerned.
• Register: Vocabulary may be formal, neutral, informal, technical, or conversational; purchase, buy, and pick up differ in register.
• Pronunciation: Stress placement can distinguish word classes and improve intelligibility, as in the noun REcord and the verb reCORD.
• Figurative use: Metaphors and idioms communicate meanings beyond the literal meanings of their individual words.

II. Compound Words: Combining Independent Words

A. compound words

Compound words are lexical units formed by combining two or more words to express one main concept.

• Closed compounds: The elements are written as one word, as in keyboard, sunlight, workplace, and deadline.
• Open compounds: The elements remain separate but function as one unit, as in credit card, post office, and traffic jam.
• Hyphenated compounds: The elements are joined by hyphens, as in well-being, editor-in-chief, and part-time.
• Grammatical patterns: Compounds may combine different word classes.
  • Noun + noun: coffee shop means a shop that sells coffee.
  • Adjective + noun: blackboard names an object rather than any board that is black.
  • Verb-related form + noun: washing machine means a machine used for washing.
  • Adjective compound: well-known author uses a compound adjective before a noun.
• Head word: In many English compounds, the final element identifies the general class; a bookshop is a kind of shop, while a shop assistant is a kind of assistant.
• Meaning: Compound meaning may not be fully predictable. A greenhouse is a glass structure for growing plants, not simply a green house.
• Plural formation: The principal element usually takes the plural: toothbrushes, passers-by, and mothers-in-law.

III. Meaning from Surroundings: Interpreting Unfamiliar Language

A. vocabulary in context

Vocabulary in context means determining a word’s meaning and effect from its surrounding sentence, paragraph, situation, and register.

• Definition clues: A sentence may explain the word directly: “Arid regions, areas receiving very little rainfall, have limited vegetation.”
• Synonym clues: A nearby equivalent can reveal meaning: “The route was hazardous, or extremely dangerous, after the snowfall.”
• Antonym clues: Contrast markers such as but, whereas, and unlike indicate opposition: “Unlike his cautious partner, Amir was impulsive.”
• Example clues: Instances clarify a category: “Renewable resources, such as sunlight, wind, and flowing water, can be naturally replenished.”
• Cause-and-effect clues: Consequences suggest meaning: “The glass was fragile, so it broke when it fell.”
• Grammatical clues: Position identifies word class. In “The committee reached a unanimous decision,” unanimous modifies decision and therefore functions as an adjective.
• Register and tone: Residence is more formal than home, while kid is less formal than child.
• Multiple meanings: Context selects the relevant sense. In “She runs a company,” runs means manages; in “She runs daily,” it describes physical movement.

IV. Relationships of Meaning: Similarity and Opposition

A. synonyms and antonyms

Synonyms express similar meanings, whereas antonyms express contrasting meanings; neither relationship should be studied without attention to context.

1. Synonyms:

   • Near-equivalence: Large, big, and enormous overlap, but enormous indicates greater size or intensity.
   • Register differences: Commence is formal, begin is neutral, and kick off is informal.
   • Collocational restrictions: English uses strong tea and powerful engine, although strong and powerful are near-synonyms.
   • Connotation: Slim is often approving, while skinny can sound critical.

2. Antonyms:

   • Gradable opposites: Hot and cold allow intermediate degrees such as warm and cool.
   • Complementary opposites: Alive and dead normally exclude each other.
   • Relational opposites: Buy and sell describe the same transaction from different viewpoints.
   • Contextual opposition: The opposite of light is dark when discussing colour, but heavy when discussing weight.

V. High-Frequency Actions: Versatile Everyday Language

A. common verbs

Common verbs are high-frequency verbs whose precise meanings depend on their objects, complements, and surrounding expressions.

• Make and do: Make commonly refers to creating or producing, as in make a plan; do refers to performing an activity, as in do research.
• Take: Its collocations include take responsibility, take notes, take a break, and take part.
• Get: It can mean receive (get a message), become (get tired), obtain (get permission), or arrive (get home).
• Have: Beyond possession, it appears in have a discussion, have difficulty, and have an opportunity.
• Give: Common combinations include give advice, give permission, and give a presentation.
• Keep: It may mean retain (keep the receipt), continue (keep working), or maintain (keep calm).
• Verb patterns: The form following a verb matters. Avoid takes an -ing form in “avoid making errors,” while decide takes a to-infinitive in “decide to leave.”
• Phrasal combinations: Particles change meaning; look up means search for information, while look after means take care of someone or something.

VI. Pronunciation and Prominence: Stress within Words

A. word stress

Word stress is the greater prominence given to one syllable through increased loudness, length, pitch movement, and vowel clarity.

• Primary stress: The symbol /ˈ/ appears before the stressed syllable: communication /kəˌmjuːnɪˈkeɪʃən/.
• Secondary stress: The symbol /ˌ/ marks a weaker additional stress in longer words.
• Two-syllable contrast: Some noun-verb pairs change stress.
  • Noun: PREsent /ˈprezənt/ means a gift or the current time.
  • Verb: preSENT /prɪˈzent/ means to introduce or display.
• Compound stress: Compound nouns often stress the first element: GREENhouse refers to a glass structure, while green HOUSE describes a house that is green.
• Suffix influence: Words ending in -tion commonly stress the preceding syllable, as in eduCAtion and inforMAtion.
• Reduced vowels: Unstressed syllables frequently contain schwa /ə/, as in the first syllable of about /əˈbaʊt/.
• Communicative importance: Incorrect stress can delay recognition even when individual consonants and vowels are accurate.

VII. Conventional Intensification: Adverbs in Natural Combinations

A. adverb collocations

Adverb collocations are conventional combinations in which an adverb modifies a verb, adjective, or another adverb.

• Adverb + adjective: Natural combinations include deeply concerned, highly successful, perfectly clear, and bitterly disappointed.
• Adverb + verb: Common patterns include strongly recommend, fully understand, firmly believe, and seriously consider.
• Degree: Slightly marks a small degree, fairly or quite a moderate degree, and extremely a high degree.
• Strong adjectives: Extreme adjectives usually combine with adverbs such as absolutely, completely, or utterly: absolutely exhausted and utterly impossible.
• Restricted choice: Grammatically possible combinations may sound unnatural. English normally uses closely related, not nearly related, when describing a strong connection.
• Meaning changes: In “He hardly works,” hardly means almost not; in “He works hard,” hard means with effort.
• Position: Frequency adverbs usually precede a main verb, as in “She often travels,” but follow be, as in “She is often busy.”

VIII. Identical Forms: Unrelated Meanings

A. homonyms

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

• Complete homonyms: These have the same spelling and pronunciation. Bank can mean a financial institution or the land beside a river.
• Homographs: These share spelling but may differ in pronunciation. Lead /liːd/ means guide, while lead /led/ names a metal.
• Grammatical identity: Homonyms may belong to the same word class, as with the two noun meanings of bat: an animal and a piece of sporting equipment.
• Contextual disambiguation: In “She deposited cash at the bank,” deposited cash selects the financial meaning; in “They sat on the river bank,” river selects the geographical meaning.
• Difference from polysemy: Homonym meanings are historically or conceptually unrelated, whereas a polysemous word has related senses. The mouth of a person and the mouth of a river share the idea of an opening.
• Communicative effect: Homonyms can create deliberate wordplay, but unintended ambiguity should be removed by adding specific context.

IX. Same Sound, Different Form: Listening and Spelling

A. homophones

Homophones are words with the same pronunciation but different spellings, meanings, or grammatical functions.

• Common pairs: Right/write, peace/piece, allowed/aloud, and weather/whether are distinguished in writing but not normally in speech.
• Grammatical distinctions: Their marks possession, there refers to a place or introduces a clause, and they’re contracts they are.
• Meaning in context: In “The principal explained the school’s main principle,” principal means the head of the school, while principle means a rule or belief.
• Listening strategy: Syntax and collocation identify the intended word. In “Please write your name,” the determiner your and object name require the verb write, not the adjective right.
• Spelling importance: Spell-checking software may not detect a correctly spelled but incorrect homophone, as in “The team lost there final match.”
• Pronunciation variation: Homophone status may depend on accent; words pronounced identically in one variety of English may be distinguished in another.

X. Figurative Comparison: Mapping One Idea onto Another

A. metaphors

Metaphors describe one concept in terms of another without using explicit comparison markers such as like or as.

• Basic structure: In “Time is money,” the abstract concept time is understood through the familiar concept money.
• Implied qualities: “Her voice was velvet” transfers the qualities of softness and smoothness from velvet to voice.
• Conceptual metaphors: Groups of expressions can share one underlying mapping. Defend a position, attack an argument, and win a debate reflect the metaphor ARGUMENT IS WAR.
• Dead or conventional metaphors: Expressions such as the foot of a mountain are so familiar that their figurative origin may be unnoticed.
• Extended metaphors: A speaker may sustain one comparison across several statements, such as presenting a project as a journey with a route, obstacles, and destination.
• Purpose: Metaphors make abstract ideas concrete, compress complex meanings, and create emotional or imaginative impact.
• Interpretation: Meaning depends on relevant shared qualities; calling an employee “a rock” suggests reliability and strength, not literal hardness.

XI. Fixed Figurative Expressions: Meaning beyond Individual Words

A. idioms

Idioms are relatively fixed expressions whose overall meanings cannot usually be calculated from the literal meanings of their individual words.

• Non-literal meaning: Break the ice means begin friendly interaction in a socially uncomfortable situation, not physically break frozen water.
• Fixed wording: Components often cannot be freely replaced. English uses spill the beans for revealing a secret; pour the peas does not carry that idiomatic meaning.
• Grammatical restriction: Some idioms permit limited changes, while others resist them. Pull strings can become pulled some strings, but its key lexical elements remain stable.
• Context and register: Get cold feet is informal and means become too nervous to proceed; it may be unsuitable in a formal legal document.
• Transparency: Some idioms are relatively clear, such as see the light, while others are opaque, such as by and large, meaning generally.
• Difference from metaphor: A new metaphor can be interpreted through comparison, whereas an idiom is a conventional expression learned as a unit.
• Cultural and communicative value: Idioms make speech vivid and natural, but excessive or unfamiliar idioms can confuse listeners, especially across cultures.
