Vocabulary for IELTS – Comprehensive Unit-by-Unit Notes

Note: The notes below synthesize the content from the provided transcript of the Vocabulary for IELTS book. They are organized by unit and cover the main topics, key vocabulary, grammar/word-formation notes, typical exam tasks, and practical tips mentioned in the source material. Where relevant, examples from the transcript are included to illustrate usage. Numbers and concise data are formatted in LaTeX where appropriate.


Unit 1 — People and Relationships

  • Topic focus: Describing people, relationships, and character; recognizing adjectives from endings; understanding noun/verb/adjective forms.

  • Key vocabulary (people):

    • Nouns for people: client, colleague, employer, parent, sibling, spouse.

    • Adjectives describing character: autonomous, consistent, conventional, cooperative (co-operative), efficient, flexible, idealistic, tolerant, vulnerable.

  • Endings and recognition tips: Adjectives often end in -able/-ible, -ic, -al, -ive, -ant/ent, -ous. Example endings and corresponding adjectives from the text: -able (e.g., capable, flexible), -ic (idealistic), -al (conventional), -ive (co-operative, efficient), -ant/-ent (tolerant, consistent), -ous (autonomous).

  • Practice focus: Distinguishing nouns for people vs. adjectives describing personality; recognizing endings to determine word class; practice exercises ask students to circle/underline associations (e.g., family vs. professional relationships) and listen for adjectives from endings in listening tasks.

  • Exam tips highlighted:

    • In Part 4 of IELTS Listening, listen for context clues and for expressions that define terms (i.e., phrases like “that is to say,” “in other words”).

    • Endings often reveal word class (e.g., -ous often adjectives).

  • Example connections: Relationship vocabulary includes client, colleague, employer (professional), and parent, sibling, spouse (family).

  • Practice structure in the unit emphasizes: labeling adjectives by endings, recognizing synonyms/antonyms, and using context to determine meaning from listening. Students also engage in short-answer tasks with tables and short fill-ins.


Unit 2 — Health

  • Topic focus: Naming health problems and treatments; recognizing synonyms and collocations; health-related vocabulary; reading on diseases of affluence vs. diseases of poverty; key verbs for treatment.

  • Health problems (nouns): addiction, allergy, cancer, dehydration, disease, infection, obesity, stroke. Note uncountable/countable distinctions (e.g., dehydration is uncountable; obesity is uncountable).

  • Subsections in the unit cover:

    • Health problems vocabulary with definitions and example sentences.

    • Verbs associated with treatment and hospital processes (administer, admit, diagnose, discharge, examine, screen, vaccinate).

    • Reading passages contrasting diseases of affluence and diseases of poverty, with risk factors (physical inactivity, diet, access to health care) and preventive measures (immunization).

  • Practical applications:

    • Understanding how risk factors contribute to different disease profiles across populations.

    • Distinguishing between actions doctors take (e.g., diagnose, administer) and patient processes (admit, discharge).

  • Exam tips:

    • IELTS Reading True/False/Not Given items require locating specific claims in the passage, and recognizing synonyms helps identify correct/incorrect statements.

    • Recognize collocations and phrasal patterns around medical topics; use context to distinguish similar terms (e.g., infection vs. infection control).

  • Notable content: The unit includes a practice exercise comparing “Diseases of Affluence” vs. “Diseases of Poverty” and a True/False/Not Given task with questions about risk factors and interventions. It also includes an exercise about replacing bold words with synonyms in a passage and ordering hospital procedures (diagnose, admit, examine, discharge, treat).

  • Practice focus: Completing word endings to form names of subjects; matching people to subjects; choosing the correct part of speech in sentences; forming and identifying definitions, evaluations, and hypotheses.

  • Exam tips:

    • Learn to recognize noun/verb/adjective forms from context and suffixes; use dictionary as needed.

    • When forming answers, ensure using the correct part of speech for the sentence context (e.g., noun vs. adjective).

  • Example application: In Task 2 Writing, students may be asked to write about the value of studying academic subjects beyond practical wealth creation; the unit provides prompts to discuss usefulness in terms of knowledge generation, language, culture, and social value.


Unit 4 — Adventure

General Study Tips from the Book

  • How to use the book effectively:

    • Begin each unit by reading Part 1 vocabulary; then work through Part 2 practice exercises; finally attempt Part 3 exam practice to simulate real IELTS conditions.

    • Use the included audio for Listening and Speaking practice; check the back of the book for the full audio script.

    • Maintain a personal vocabulary notebook; record key definitions, word forms, common collocations, and example sentences.

    • Review the Collocations list at the back of the book to reinforce word-use patterns.

  • Exam strategies highlighted throughout:

    • In Listening, listen for cue phrases and synonyms; in Reading, look for synonyms and superordinate terms to identify True/False/Not Given statements; in Writing, vary vocabulary and don’t rely on memorized model answers; in Speaking, demonstrate broad vocabulary with precise nuances and accurate pronunciation.

  • Pronunciation and stress:

    • Practice word stress in multisyllabic terms; ensure accurate SLP (sound/letter) mapping for sibilants and related consonants; use the track examples to hear native pronunciation patterns.

  • Paraphrasing and word-form knowledge:

    • Learn to derive noun/verb/adjective forms from root words; practice ending patterns (-ics, -logy, -y, -al, -ous, -ant/ent, -ive) to expand your ability to recognize and produce related forms.


Quick Reference: Key Formulas/Numeric References

  • Distinct numeric/data references appear throughout the units in examples (e.g., 600 calories per day; 350 million adults with Type 2 diabetes; sea levels rising by no more than 1 metre; time intervals such as decades, centuries, and millennia). When these figures are discussed, present them in LaTeX for clarity:

  • Example: The recommended daily calorie intake in one exercise is 600 extcal/day600\ ext{cal/day}.

  • Total incidence figures for health topics (illustrative): 3.5×1083.5\times 10^8 adults with Type 2 diabetes (as cited in some readings).

  • Time intervals and growth rates are often expressed as percentages or orders of magnitude (e.g., doubling over 30 years), which can be captured succinctly in graphs or in a sentence like: The incidence increased from X to 2X2X over tt years.

If you’d like, I can tailor these notes to a single unit (e.g., Unit 9 on Global Warming) or expand any unit with more examples, definitions, and practice items. I can also convert these notes into flashcards or a printable study guide.
