Parts of Speech – Study Notes (Coast Guard – English Language)
Target Audience:
Candidates preparing for competitive exams (e.g. IIT‑JEE, UPSC, BPSC, etc.) who need a crisp, exam‑oriented understanding of the six (sometimes seven) parts of speech.
Why this matters:
Many competitive exams test your command over English grammar through sentence completion, odd‑one‑out, paraphrasing, and error‑spotting questions. Knowing the six parts of speech and their “fingerprints” lets you spot errors, choose the right word, and construct grammatically correct sentences.
1. Quick Reference Table
| # | Part of Speech | Typical Function | Key Features / “Fingerprints” | Common Forms / Derivatives |
|---|---|---|---|---|
| 1 | Noun | Person, place, thing, idea | Can be preceded by article/quantifier; takes plural & possessive | noun → nouns*, nouning*, nounness* |
| 2 | Pronoun | Replaces noun | Pronouns: he, she, it, they, this, that, who, whom, whose | pronoun → pronounly* (adv.) |
| 3 | Verb | Action, state, or occurrence | Can be transitive/ intransitive, finite/non‑finite | verb → verbs*, verbing*, verbed* |
| 4 | Adjective | Describes noun | Usually precedes noun or follows copular verb | adj → adjly*, adjness* |
| 5 | Adverb | Modifies verb, adjective, or adverb | Often ends in ‑ly | adv → advly*, advness* |
| 6 | Preposition | Shows relation between noun/pronoun & other words | Prepositions are followed by a noun phrase (object) | prep → preps* (rare; e.g., in → ins in plural sense) |
| 7 | Conjunction | Connects words, phrases, clauses | Coordinating, subordinating, correlative | conj → conjs* (e.g., and → ands in plural sense) |
| 8 | Interjection | Expresses emotion | Stand‑alone, often followed by a comma | interj → interjs* (e.g., oh → oho) |
Note: Some words may belong to multiple parts of speech (e.g., light as noun vs. adjective). Context is key.
2. In‑Depth Explanation
2.1 Noun
- Definition: A lexical word naming a person, place, thing, event, quality, or abstract idea.
- Core Properties:
- Can be countable or uncountable.
- May have plural (cats) or singular (cat).
- Can be possessive (John’s book).
- Usually takes determiners (the, a, this, that, some, many).
- Derivational Morphology:
- noun → nouns* (plural)
- noun → nounness* (abstract noun)
- noun → nouning* (gerund noun)
- Tricky Point: Some nouns can also function as adjectives when placed before another noun (e.g., school book).
2.2 Pronoun
- Definition: A word that stands in for a noun or noun phrase.
- Types:
- Personal (he, she, they)
- Demonstrative (this, that)
- Interrogative (who, whom)
- Relative (who, which, that)
- Possessive (his, her, their)
- Reflexive (himself, herself)
- Core Properties:
- Must agree in number and gender with the noun it replaces.
- Cannot take a determiner (*not the she).
- Tricky Point: Who is used as subject, whom as object (though whom is often replaced by who in colloquial speech).
2.3 Verb
- Definition: A word that expresses action, state, or occurrence.
- Core Properties:
- Can be finite (conjugated) or non‑finite (infinitive, participle, gerund).
- Has tense (past, present, future) and aspect (simple, continuous, perfect, perfect‑continuous).
- Transitivity: Transitive verbs take an object (She reads a book), intransitive do not (He sleeps).
- Derivational Morphology:
- verb → verbs* (3rd person singular)
- verb → verbing* (present participle/gerund)
- verb → verbed* (simple past)
- Tricky Point: To can function as a preposition (to the store) or an infinitive marker (to eat). Distinguish based on function.
2.4 Adjective
- Definition: A word that modifies a noun or pronoun.
- Core Properties:
- Usually precedes the noun (a red apple), but may follow a linking verb (The apple is red).
- Can be **gradable
