🔠 When to Use Capital Letters

What you’ll learn

1. Big Letters and Little LettersRecognize that every letter has a capital (big) and lowercase (small) form, and that capitals signal a special word.Each letter has two forms: a big capital and a small lowercase letter. Capital letters act as a signal that a word is special or important — the idea that ties the whole course together.
2. Start Every Sentence With a CapitalAlways begin a sentence with a capital letter.The first word of every sentence starts with a capital letter, marking where a new idea begins. This makes writing easier to read and is the most common use of capitals.
3. Names of People and PetsCapitalize the names of people and pets.Names of people and pets are special, so they always begin with a capital letter, while ordinary words like 'girl' or 'dog' stay lowercase. Learners practise telling names apart from common words.
4. Names of PlacesCapitalize the names of places such as towns, cities, and countries.Place names — towns, cities, and countries — are special names and begin with a capital letter, just like people's names. Signs and writing show place names always starting big.
5. Days of the WeekCapitalize the seven days of the week.Each day of the week is a special name and begins with a capital letter. Learners meet all seven days and practise telling day names from ordinary words.
6. The Special Word IAlways write the word 'I' as a capital, and recall every rule for capital letters.The single-letter word 'I' is always capitalized, even in the middle of a sentence. The lesson reviews every capital-letter rule: sentence starts, people and pets, places, days of the week, and the word I.
