- ๐ Worksheet: Capitalisation Rules
1. Why Capitalisation Matters
Capital letters serve three main purposes: they mark the beginning of a new sentence, they distinguish proper nouns from common nouns, and they add emphasis or respect in specific contexts. A text written entirely in lowercase feels lazy and unprofessional; a text with random capitals feels chaotic. Consistent capitalisation is a hallmark of a careful writer.
2. First Word of a Sentence
The first word of every complete sentence must begin with a capital letter. This rule applies universally.
- Correct: The train arrived late.
- Incorrect: the train arrived late.
This rule also applies to the first word of a direct quotation that is a full sentence.
- She turned and said, "Let us go home now."
3. Proper Nouns & Proper Adjectives
A proper noun names a specific person, place, organisation, or thing. Proper adjectives are adjectives formed from proper nouns.
- People: Mahatma Gandhi, Riya, Dr. Sen
- Places: India, Uttar Pradesh, the Ganga, the Sahara Desert
- Organisations & Brands: United Nations, CBSE, Nike, Taj Mahal Palace Hotel
- Proper Adjectives: Indian culture, Shakespearean tragedy, Victorian architecture
Note: Common nouns are not capitalised. Write "a country", but "India". Write "a river", but "the Yamuna".
4. Titles, Headings & Direct Address
- Titles before names: Capitalise titles when they appear directly before a person's name. President Murmu, Prime Minister Modi, Dr. Kalam.
When the title stands alone, use lowercase: The prime minister addressed the nation. - Direct address: When you call someone by a title instead of their name, capitalise it. Will you help me, Mother? I asked Father for permission.
- Headings and titles of works: Capitalise the first letter of every major word. Articles and short prepositions usually stay lowercase. The Wind in the Willows, A Tale of Two Cities
5. Days, Months, Holidays & Historical Events
Days of the week, months of the year, and the names of holidays and festivals always take a capital letter. Seasons (spring, summer, autumn, winter) are common nouns and are not capitalised unless they start a sentence or appear in a title.
- Correct: Monday, January, Diwali, Christmas, Independence Day
- Incorrect: monday, january, diwali
- Correct: I love the spring season. We will travel in winter.
6. Capitalisation in Direct Speech
When you write direct speech, the first word inside the quotation marks always starts with a capital letter if it is a complete sentence. If the quote is broken into two parts by a reporting clause, the second part usually starts with a lowercase letter (unless it begins a new sentence).
- She said, "The movie was fantastic."
- "I am tired," he said, "and I want to rest."
- "Stop!" he shouted. "There is danger ahead." (New sentence after the reporting clause, so capitalised.)
7. The Pronoun "I" and Other Special Rules
- The pronoun I: Always written in capital, no matter where it appears. That is exactly what I meant.
- Abbreviations and acronyms: Some abbreviations are fully capitalised. UNESCO, NASA, USA, FIR, PDF
- Specific course names: I am taking History and Mathematics this semester. (General subjects: lowercase. Specific course titles: capitalised.)
- The word "God" when referring to a monotheistic deity, and all pronouns referring to God are often capitalised. Thank God. The Almighty.

Why Capitalisation is the Mark of a Polished Writer
Capitalisation may seem like a minor detail, but it speaks volumes about your professionalism as a writer. A single lowercase "i" can make an otherwise brilliant essay look careless. In board exams, correct capitalisation in letters, notices, and essays contributes directly to your marks for expression. In the professional world, errors in capitalisation in a resume or application can cost you an opportunity. The rules are simple, but consistent application requires practice. Make it a habit to proofread your work specifically for capital letters before submitting any piece of writing.
