What Is English Grammar?
Grammar is the set of rules that explains how words combine to form clear sentences. Good grammar helps you communicate accurately, earn better grades, and make a strong impression at work.
Poor grammar: He go to work every day. Correct grammar: He goes to work every day.
Why Learning Grammar Is Important
- Students: better grades and clearer essays and reports.
- Job seekers: polished resumes and application letters, and more confident interviews.
- Professionals: professional emails, reports, and presentations.
Parts of Speech
English words fall into 8 parts of speech: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections.
Nouns
A noun names a person, place, thing, or idea. Examples: teacher, school, computer, honesty.
- Common: city, student
- Proper: Cebu, Maria
- Collective: team, family, committee
- Abstract: honesty, freedom, patience
Example: The teacher praised the team for their honesty.
Mini exercise: Find the nouns in “Maria bought a laptop in Manila.” Answer: Maria, laptop, Manila.
Pronouns
Pronouns replace nouns: I, you, he, she, it, we, they (subject); me, him, her, us, them (object); mine, yours, theirs (possessive).
Example: Maria is a nurse. She works at a hospital.
Common mistake: ~~Me and him went home.~~ → He and I went home.
Mini exercise: “Give the files to (he/him).” Answer: him, because it is the object of “to”.
Verbs
Verbs show action or state: run, walk, speak, write, be.
- Action verbs show what someone does: She writes reports.
- Helping verbs (is, are, was, have, will, can) support the main verb: She is writing.
Mini exercise: Find the verb and helping verb in “They have finished.” Answer: Helping verb: have. Main verb: finished.
Adjectives
Adjectives describe nouns: beautiful, tall, smart.
Example: A smart student passed the difficult exam.
Mini exercise: Find the adjectives in “The red car is fast.” Answer: red, fast.
Adverbs
Adverbs modify verbs, adjectives, or other adverbs: quickly, slowly, carefully. Many end in -ly.
Example: She answered carefully.
Mini exercise: Find the adverb in “He walked slowly home.” Answer: slowly.
Prepositions
Prepositions show relationships of place, time, or direction: in, on, at, under, behind.
Example: The report is on the desk under the lamp.
Mini exercise: Find the preposition in “We met at noon.” Answer: at.
Conjunctions
Conjunctions join words or clauses: and, but, or, because.
Example: I studied hard because the exam was difficult.
Mini exercise: Join “I was tired. I kept working.” with “but”. Answer: I was tired, but I kept working.
Interjections
Interjections express emotion: Wow! Oops! Oh!
Example: Wow! You passed the exam!
Sentence Structure
A sentence is a group of words with a subject and a predicate that expresses a complete thought. There are four types:
| Type | Purpose | Example |
|---|---|---|
| Declarative | States | I enjoy reading books. |
| Interrogative | Asks | Do you enjoy reading books? |
| Imperative | Commands | Read this book. |
| Exclamatory | Shows strong feeling | What a wonderful book! |
Subject-Verb Agreement
The verb must match its subject in number. Singular subjects take singular verbs; plural subjects take plural verbs.
Singular: She works. Plural: They work.
Common Errors
- ~~The boys is playing.~~ → The boys are playing.
- ~~Each of the employees have a badge.~~ → Each of the employees has a badge.
- ~~The news are good.~~ → The news is good.
Practice: “My brothers (live/lives) in Cebu.” Answer: live, because “brothers” is plural.
Verb Tenses
| Tense | Use | Example |
|---|---|---|
| Present | Habits, facts | I work every day. She works here. |
| Past | Finished actions | I worked yesterday. He wrote a letter. |
| Future | Planned or predicted | I will work tomorrow. |
Common Mistakes
- ~~Yesterday, I go to school.~~ → Yesterday, I went to school.
- ~~Tomorrow, she takes the exam.~~ → Tomorrow, she will take the exam.
Practice: “Last week, I ___ (submit) my application.” Answer: submitted.
Common Grammar Mistakes
| Words | Meaning and example |
|---|---|
| Their / There / They’re | Their = belonging to them; there = place; they’re = they are. Example: Their bags are there because they’re late. |
| Your / You’re | Your = belonging to you; you’re = you are. Example: You’re sure your answer is right. |
| Its / It’s | Its = belonging to it; it’s = it is. Example: It’s clear the dog wagged its tail. |
| Then / Than | Then = time; than = comparison. Example: She is taller than he is, then she left. |
| Affect / Effect | Affect (verb) = influence; effect (noun) = result. Example: Stress can affect sleep; the effect is fatigue. |
