Why "Two Childs" Is Wrong: The English Basics Cheat Sheet You'll Keep Coming Back To
Quick guess: what's the plural of "child"? If you said "childs," don't worry — almost every beginner does. The real answer is "children." English has a handful of basic rules that look small but instantly reveal whether you're still a beginner when you get them wrong.
The good news: there aren't many of them, and you can learn all of them in one read. This article covers the three most important foundations — plural nouns, articles (a/an/the), and subject pronouns — in a format built to be reopened any time you forget, like a personal cheat sheet.
1. Plural Nouns (One vs. More Than One)
The general rule: add -s to the end of the word.
book → books car → cars dog → dogs
But some words need special treatment depending on how they end.
| Word ending | Rule | Example |
|---|---|---|
| -s, -ss, -sh, -ch, -x, -z | add -es | box → boxes, watch → watches |
| consonant + -y | change y to i, add -es | city → cities, baby → babies |
| vowel + -y | just add -s | boy → boys, day → days |
| -f / -fe | change to -ves | leaf → leaves, knife → knives |
Irregular plurals (no formula — you just have to memorize these):
| Singular | Plural |
|---|---|
| man | men |
| woman | women |
| child | children |
| person | people |
| tooth | teeth |
| foot | feet |
Words that don't change at all: sheep, fish, deer — the singular and plural forms are identical.
💡 Memory trick: the six irregular words above fit into one silly sentence: "Men and women take children's teeth and feet." Learn that one sentence, and you've learned the most common irregular plurals in English.
2. A, An, The — When to Use Which
This is one of the most confusing parts for beginners, even though the rule is simple once you know the trick: listen to the sound, not the first letter.
| Article | Used for | Example |
|---|---|---|
| a | one thing, not specific, starts with a consonant sound | a book, a car |
| an | one thing, not specific, starts with a vowel sound | an apple, an hour |
| the | a specific thing — both speaker and listener already know which one | the book on the table |
| (no article) | general statements, plurals, or uncountable things | Cats are cute. I like music. |
The classic trap: an hour (the "h" is silent) and a university (the "u" is pronounced like "y"). That's why you shouldn't look at the letter — listen to the sound that actually comes out of your mouth.
💡 Memory trick: say the word right after "a" or "an" slightly out loud. If your tongue glides smoothly into a vowel sound (a-e-i-o-u), use "an." If there's a hard consonant stop, use "a." This is more reliable than memorizing letters.
3. Subject Pronouns (I, You, He, She, It, We, They)
This part looks easy, but it's exactly where Indonesian speakers slip up most often — and for a very understandable reason.
Indonesian has one all-purpose word: "dia." It can mean "he," "she," and sometimes even gets used loosely for animals. English has no equivalent all-purpose word — you're required to choose based on the gender of the person you're talking about.
| Noun | Pronoun |
|---|---|
| Tom (male) | he |
| Maria (female) | she |
| a book, a car, a cat (thing/animal) | it |
| Tom and Maria / my parents | they |
| Tom and I | we |
| the person you're speaking to | you |
💡 Memory trick for Indonesian speakers specifically: every time you're about to say "dia" in English, pause and ask yourself one question: "Male, female, or not a person at all?" If it's not a person — an object, animal, place, or idea — always use "it," never "he" or "she." This is the single most common mistake that makes a sentence sound off to a native ear.
Cheat Sheet — Save This
- Plurals: add -s (default), -es (after -s/-sh/-ch/-x/-z), change -y to -ies (after a consonant). Memorize the 6 irregulars: men, women, children, people, teeth, feet.
- A/an: listen to the sound, not the letter. The: for a specific thing both people already know.
- He/she/it: choose based on gender for people; always "it" for objects, animals, and places.
