1. Introduction to Numbers in English Grammar (परिचय)

In English grammar, Numbers help us express how many people, things, or ideas we are referring to. They indicate quantity (how much or how many) and position (order of items). Without Numbers, communication becomes vague, incomplete, and ambiguous.

Hindi Meaning:

Numbers का मतलब है — किसी वस्तु, व्यक्ति या विचार की संख्या या क्रम बताने वाले शब्द।

English learners frequently encounter Numbers in daily speech:

• “One book”
• “Two students”
• “First day”
• “Hundreds of people”

Each of these expressions holds a quantitative or positional meaning.

2. Why Learning Numbers Matters (क्यों ज़रूरी है)

A strong understanding of Numbers helps learners in:

• forming grammatically correct sentences
• improving accuracy in communication
• describing objects and events better
• using plural forms correctly
• strengthening foundational grammar skills

When beginners learn Numbers efficiently, their overall command of English improves noticeably. Their sentences sound clearer, more precise, and more structured.

3. Types of Numbers in English (Numbers के प्रकार)

Broadly, English grammar divides Numbers into two categories:

1. Cardinal Numbers – Counting numbers
2. Ordinal Numbers – Position or order numbers

Let us explore each type in detail with Hindi meanings and examples.

4. Cardinal Numbers (गणनात्मक संख्या)

Cardinal Numbers are used for counting people or objects. These are the very first Numbers learners memorize when beginning English.

Hindi Meaning:

Cardinal Numbers वे संख्या शब्द होते हैं जो “कितने” बताते हैं।

Examples include: One, Two, Three, Four, Ten, Hundred, Thousand, etc.

4.1 Common Cardinal Numbers with Hindi Meaning

English	Hindi Meaning
One	एक
Two	दो
Three	तीन
Four	चार
Five	पाँच
Ten	दस
Twenty	बीस
Hundred	सौ
Thousand	हज़ार

Cardinal Numbers answer the question “How many?”
For example:

• I have two pens. – मेरे पास दो पेन हैं।
• She bought five apples. – उसने पाँच सेब खरीदे।

4.2 Usage of Cardinal Numbers in Daily Sentences

1. There are three students waiting outside.
   – बाहर तीन छात्र इंतज़ार कर रहे हैं।
2. He wrote ten pages today.
   – उसने आज दस पन्ने लिखे।
3. She has one brother and two sisters.
   – उसके एक भाई और दो बहनें हैं।
4. They planted hundreds of trees.
   – उन्होंने सैकड़ों पेड़ लगाए।

These sentences show how cardinal Numbers make everyday communication clearer and more specific.

5. Ordinal Numbers (क्रम-सूचक संख्या)

Ordinal Numbers indicate the position or rank of something.

Hindi Meaning:

Ordinal Numbers वे शब्द होते हैं जो किसी व्यक्ति या वस्तु का “क्रम” बताते हैं।

Examples: First, Second, Third, Fourth, Tenth, Twentieth, etc.

5.1 Common Ordinal Numbers with Hindi Meaning

English	Hindi Meaning
First	पहला
Second	दूसरा
Third	तीसरा
Fourth	चौथा
Fifth	पाँचवाँ
Tenth	दसवाँ
Twentieth	बीसवाँ

Numbers like these allow speakers to express sequence and order.

5.2 Usage of Ordinal Numbers in Daily Life

1. She stood first in her class.
   – वह अपनी कक्षा में पहली आई।
2. This is the second time I am calling you.
   – मैं तुम्हें दूसरी बार कॉल कर रहा हूँ।
3. His house is on the third floor.
   – उसका घर तीसरी मंज़िल पर है।
4. Today is the fourth meeting of the month.

7. Rules for Writing Numbers in English (महत्वपूर्ण नियम)

To use Numbers effectively, learners must be aware of basic grammatical rules. These rules make sentences coherent and professional.

---

7.1 Numbers in Words vs. Digits

When to write in words:

• Small Numbers (usually 1–10)
• Beginning of sentences
• Formal writing

Example:

• “Three people attended the meeting.”
• “Seven days are left.”

When to use digits:

• Large Numbers
• Dates
• Addresses
• Percentages
• Statistics

Example:

• 120 students
• 25% discount
• 2025 (year)

---

7.2 Hyphenated Numbers

Compound Numbers between 21–99 that are not multiples of 10 take a hyphen.

Examples:

• Twenty-one – इक्कीस
• Forty-five – पैंतालीस
• Sixty-eight – अड़सठ

This rule helps maintain clarity and standardization in writing.

---

7.3 Plural Form with Measurements

When expressing measurements, certain Numbers follow a singular noun even though the quantity is plural.

Examples:

• A five-minute break (not “five-minutes break”)
• A two-hour meeting
• A three-day trip

However:

• The break lasted five minutes.
• We waited two hours.

The noun becomes singular only when Numbers precede the noun as a compound modifier.

---

7.4 Comma Usage in Large Numbers

For readability, commas are used in large Numbers.

Examples:

• 1,000
• 25,000
• 1,50,000 (Indian style)
• 150,000 (International style)

Beginners should familiarize themselves with both formats, as English content may follow either.

---

8. Collective Use of Numbers (सामूहिक प्रयोग)

Sometimes Numbers are used in expressions that refer to approximate or collective quantities.

Examples:

• Dozens of people – दर्जनों लोग
• Hundreds of birds – सैकड़ों पक्षी
• Thousands of fans – हजारों प्रशंसक

Such usages add depth and emphasis to statements.

9. Fractions and Decimals (भिन्न और दशमलव)

9.1 Fractions (भिन्न)

Fractions combine Numbers to express parts of a whole.

Examples:

• 3/4 – Three-fourths – तीन-चौथाई

Usage:

• He drank half a glass of milk.
• They completed three-fourths of the work.

9.2 Decimals (दशमलव)

Decimals express precise numerical values.

Examples:

• 1.5 – One point five
• 3.75 – Three point seven five

• The distance is 4.5 kilometers.
• The price increased by 2.75%.

Learning fractions and decimals helps learners handle mathematical and scientific contexts in English.

10. Numbers in Plurals (बहुवचन में Numbers का प्रयोग)

When Numbers come before countable nouns, the noun is always in plural form (except when used as modifiers, discussed earlier).

• Two chair
• Five book

Correct pluralization is essential for grammatical accuracy.
