Unit I: Vocabulary Building
Vocabulary building is the foundational process of expanding your lexicon to improve precision, clarity, and effectiveness in written and spoken communication. Mastering vocabulary involves understanding how words are constructed, where they originate, and how their meanings shift based on prefixes, suffixes, context, and structural abbreviations.
1. The Concept of Word Formation
Word formation is the creation of new words using existing linguistic elements such as roots, bases, prefixes, and suffixes. In English, word formation operates primarily through several key morphological processes:
WORD FORMATION PROCESSES
|
+—————–+———————+———————+—————–+
| | | | |
AFFIXATION COMPOUNDING BLENDING CLIPPING CONVERSION
(Prefix/Suffix) (Two full words) (Merged components) (Shortened word) (Part of speech shift)
Key Processes of Word Formation
Affixation (Derivation & Inflection): Adding prefixes or suffixes to a base word to alter its meaning or change its grammatical category.
Example: Happy (Adjective) → Unhappy (Adjective with opposite meaning) → Happiness (Noun).
Compounding: Joining two or more complete base words together to create a single new term with a distinct meaning.
Example: Book + Shelf = Bookshelf | Break + Through = Breakthrough
Blending (Portmanteau Words): Combining parts of two distinct words to form a new word that merges their meanings.
Smoke + Fog = Smog | Web + Seminar = Webinar | Breakfast + Lunch = Brunch
Clipping: Shortening a longer word without changing its original meaning or part of speech.
Advertisement → Ad | Laboratory → Lab | Influenza → Flu
Conversion (Zero Derivation): Changing the grammatical category (part of speech) of a word without modifying its spelling or structure.
Email (Noun: “I sent an email.”) → Email (Verb: “I will email you the report.”)
Run (Verb: “They run fast.”) → Run (Noun: “I went for a run.”)
Run (Verb: “They run fast.”) → Run (Noun: “I went for a run.”)
2. Foreign Root Words and Derivatives in English
Modern English is a polyglot language that has borrowed heavily from ancient and foreign languages—most notably Latin and Greek. A root word is the primary lexical unit of a word that carries its core meaning and cannot be reduced further.
DERIVATION OF WORDS FROM ROOT WORDS
|
[ PREFIX ] + [ ROOT ] + [ SUFFIX ]
|
Example: Re- + spect + able = Respectable
Common Foreign Root Words & Their English Derivatives
| Root Word | Origin | Meaning | English Derivatives & Examples |
|---|---|---|---|
| Chron | Greek | Time | • Chronological: Arranged in order of time. • Anachronism: Something out of its proper time period. • Synchronize: Occurring at the exact same time. |
| Cred | Latin | Believe, Trust | • Credible: Believable or convincing. • Incredible: Extraordinary; hard to believe. • Credential: A document giving authority/trust. |
| Graph / Gram | Greek | Write, Draw | • Autograph: A person’s signature written by hand. • Biography: Written account of a person’s life. • Telegraph: System for transmitting messages writing. |

| Path | Greek | Feeling, Suffering | • Empathy: Ability to understand another’s feelings. • Apathy: Lack of feeling or interest. • Pathology: The study of diseases and suffering. |
3. Prefixes and Suffixes from Foreign Languages
Affixes are morphemes attached to a root or base word. They are categorized as prefixes (attached at the beginning) or suffixes (attached at the end).
TYPES OF AFFIXES

PREFIXES SUFFIXES
(Attached to the beginning) (Attached to the end)
| |
• Modifies or reverses meaning • Changes part of speech or state
• Examples: Un-, Anti-, Re- • Examples: -tion, -able, -ity
Foreign Prefixes in English
Prefixes modify the core meaning of the root word, often indicating direction, negation, time, or quantity.
| Prefix | Origin | Meaning | Applied Examples & Meanings |
|---|---|---|---|
| Anti- | Greek | Against, Opposite | • Antidote: Medicine preventing effects of poison. • Antisocial: Hostile or opposed to social order. |
| Bene- | Latin | Good, Well | • Benefactor: A person who gives help or money. • Benevolent: Well-meaning and kindly. |

| Post- | Latin | After, Later | • Postpone: Delay or cause to take place at a later time • Postscript (P.S.): An addition after a signed letter. |
Foreign Suffixes in English
Suffixes typically alter the part of speech of the root word (e.g., turning a verb into a noun, or a noun into an adjective).
| Suffix | Origin | Function / Meaning | Applied Examples & Meanings |
|---|---|---|---|
| -able / -ible | Latin | Able to be / Worthy of (Forms Adjectives) | • Capable: Having ability to achieve something. • Visible: Able to be seen by the human eye. |
| -tion / -sion | Latin | State, Quality, or Action (Forms Nouns) | • Clarification: State of making something clear. • Decision: Action of making up one’s mind. |
| -ist | Greek | One who practices / believes (Forms Nouns) | • Optimist: Person inclined to expect good outcomes. • Specialist: Person highly skilled in a specific field. |
| -ology | Greek | Field of Study / Science (Forms Nouns) | • Biology: The study of living organisms. • Psychology: The study of the mind and behavior. |
| -ous / -ious | Latin | Full of / Having quality of (Forms Adjectives) | • Dangerous: Full of danger or risk. • Ambitious: Possessing strong determination to succeed. |
4. Synonyms, Antonyms, and Contextual Usage
A robust command of English requires selecting the precise word according to tone, formality, and subtle shades of meaning.
LEXICAL RELATIONSHIPS

SYNONYMS ANTONYMS
(Similar core meanings, (Opposite or contrasting
varying nuances) meanings)
Synonyms
Synonyms are words that have the same or nearly the same meaning as another word in the same language. While core meanings align, synonyms often vary by nuance, emotion, or degree of formality.
Example 1 (Degree of Intensity):
Big (Neutral) → Large (Formal) → Enormous (Very large) → Gigantic (Extremely large).
Example 2 (Contextual Precision):
Buy (General everyday conversation)
Purchase (Formal or professional business transactions)
Purchase (Formal or professional business transactions)
Antonyms
Antonyms are words that express opposite or contrasting meanings. They are classified into three distinct categories:
- Gradable Antonyms: Represent points on a continuous scale (e.g., Hot ↔ Cold, Rich ↔ Poor).
- Complementary (Binary) Antonyms: Absolute opposites with no middle ground (e.g., Alive ↔ Dead, True ↔ False).
- Relational (Converse) Antonyms: Express a reciprocal relationship (e.g., Teacher ↔ Student, Buy ↔ Sell, Parent ↔ Child).
5. Standard Abbreviations, Acronyms, and Initialisms
Abbreviations shorten words and phrases to save space, increase efficiency, and simplify written and spoken business communications.

Classification of Abbreviations
| Category | Structural Rule | Examples & Descriptions |

| Initialisms | Formed from initial letters of a phrase but pronounced letter-by-letter. | • CEO: Chief Executive Officer. • HR: Human Resources. • URL: Uniform Resource Locator. |
| Latin Abbreviations | Traditional shortened Latin phrases used standardly in academic and business writing. | • e.g. (exempli gratia): For example. • i.e. (id est): That is / In other words. • etc. (et cetera): And so forth. • vs. (versus): Against. • NB (nota bene): Note well / Take special note. |
