Capitalization means using a big letter (A, B, C) at the start of certain words. It is one of the first skills of clear writing. Get it right and your writing instantly looks correct and professional. This lesson covers every rule you need.

1. The first word of a sentence

Always start a sentence with a capital letter, whatever type it is.

Type Example
Statement My brother is at home.
Command Close the door.
Question Are you a student?
Exclamation Look out!

2. The pronoun “I”

The word I is always a capital letter, anywhere in a sentence: “Aisha and I are friends.”

3. Names of people, titles & job titles

Capitalize people’s names. Capitalize a job name only when it is used as a title before a name. Put a period after abbreviated titles.

Capital (title) Small (not a title)
Professor Basker She is a professor.
Dr. Kim, Ms. Park He is a doctor.

4. Places

Capitalize cities, countries, continents, and specific place names: seas, oceans, lakes, rivers, deserts, mountains, planets, streets, buildings, schools, and companies.

  • Cities & countries: Cairo, Malaysia, London
  • Place names: the Nile, the Pacific Ocean, Jeju Island
  • Buildings & schools: Seoul National University, the Hilton Hotel
Sun, moon & seasonsDo not capitalize sun, moon, or the seasons (spring, summer, autumn, winter). Do capitalize the months and days: January, Monday.

5. Languages, nationalities, days & months

Always capital Examples
Languages / nationalities Arabic, English, Japanese
Days of the week Sunday, Monday
Months of the year July, February

6. Brand names & acronyms

Capitalize a brand name but not the product: “a Samsung television.” Capitalize acronyms made from first letters: the UN, the USA, the UAE, TV, ID.

Tutor tip for Arabic speakersArabic has no capital letters, so this rule is brand-new for many Arabic speakers — it feels strange at first, and that is completely normal. Two habits fix 90% of mistakes: (1) capitalize the very first letter of every sentence, and (2) always write I as a capital. Build those two into muscle memory first, then add names and places.

Examples from EduCareer

  • Aisha studies English and Arabic every Monday.
  • Omar and I visited Dubai in the UAE last July.
  • Yusuf lives on Victoria Street near the Hilton Hotel.
Common mistakes

i study english on monday.  →  I study English on Monday.

my friend omar lives in cairo.  →  My friend Omar lives in Cairo.

We go to the beach every Summer.  →  We go to the beach every summer. (seasons are small)
