Capitalization Rules — Capitalize proper nouns and titles...

SECTION 1

Historical Context & Motivation

Have you ever wondered why some words in a sentence start with a big letter and others don't? Capitalization (using an uppercase letter at the start of a word) has been part of written language for over a thousand years. It helps readers quickly spot important names, places, and ideas.

In the earliest days of writing, there was no difference between big and small letters. Ancient Romans carved everything in what we now call uppercase. Over time, scribes (people who copied books by hand) developed smaller, rounder letters to write faster. Eventually, writers began mixing the two styles to create the system we use today.

700s

Lowercase Letters Appear

Monks in Europe began using smaller letters alongside capitals to copy books more quickly. This created two versions of each letter.

1400s

The Printing Press Arrives

Johannes Gutenberg's printing press forced printers to decide exactly when to use capital letters. Rules started becoming more consistent across books.

1700s

Modern Rules Take Shape

English grammar books set clear capitalization rules. Writers agreed to capitalize proper nouns (specific names) and the first word of every sentence.

Standardized Testing & Formal Writing

Tests like the SHSAT expect you to know when a word should — or should not — be capitalized. Getting it right shows strong editing skills.

On the SHSAT Revising and Editing Part B, you'll read passages that contain capitalization errors. Your job is to spot them and choose the correct fix. The question this lesson answers is simple but powerful: Which words deserve a capital letter, and which ones don't?

SECTION 2

Core Principles of Capitalization

Capitalization boils down to one big idea: proper nouns (words that name a specific person, place, or thing) get capitalized, while common nouns (general words for people, places, or things) do not. Let's break this into four key principles.

Proper Nouns vs. Common Nouns

A proper noun names one specific thing: Central Park, Dr. Garcia. A common noun names any member of a group: park, doctor.

Titles of People

Capitalize a title when it comes right before a person's name: President Lincoln. Don't capitalize it when it stands alone: the president spoke.

Titles of Works

In titles of books, songs, and movies, capitalize the first word, last word, and all important words. Do not capitalize short words like the, of, and, in unless they start or end the title.

Other Must-Capitalize Categories

Always capitalize days of the week, months, holidays, languages, nationalities, and historical events. Do not capitalize seasons (winter, spring) unless they start a sentence.

✦ KEY TAKEAWAY

Think of a capital letter like a name tag. If someone (or something) has its own unique name — like a person, a city, or a holiday — it wears a name tag. That name tag is the capital letter. Words that describe general things, like "city" or "holiday," don't get a name tag because they could refer to any city or holiday.

SECTION 3

Visual Explanation — Proper vs. Common Nouns

The left column shows proper nouns that always get a capital letter. The right column shows their common noun counterparts that stay lowercase.

Notice the pattern in the diagram above. Every time you can replace a word with any other member of its group, that word is a common noun and stays lowercase. "The doctor" could be any doctor, so it's lowercase. But "Dr. Maya Angelou" names one specific person, so every word gets a capital letter.

SECTION 4

How Capitalization Rules Work in Detail

Rule 1 — First Word of a Sentence

Always capitalize the first word of every sentence. This one is straightforward. Even if the word is normally lowercase, it gets a capital at the start: "The dog ran fast." The word "the" is not special, but because it starts the sentence, it gets a capital T.

Rule 2 — Proper Nouns (Specific Names)

This is the rule the SHSAT tests most often. A proper noun is the official name of a specific person, place, organization, or thing. Capitalize every important word in the name. Here are the main categories you'll see on the test.

People and pets: Rosa Parks, Buddy the dog
Geographic names: the Pacific Ocean, Mount Everest, Brooklyn
Organizations and institutions: the United Nations, Bronx High School of Science
Languages and nationalities: Spanish, Japanese, American
Historical events and periods: the Renaissance, World War II
Days, months, and holidays: Friday, October, Thanksgiving

Rule 3 — Titles of People

Capitalize a title only when it is used directly before a person's name: "Mayor Adams spoke at the event." When the title is used alone or after the name, keep it lowercase: "The mayor spoke at the event." This is a tricky area that shows up a lot on the SHSAT.

Rule 4 — Titles of Works (Books, Songs, Movies)

When you write the title of a book, movie, song, or article, capitalize the first word, last word, and all major words. Short, unimportant words like a, an, the, and, but, or, in, of, to, for stay lowercase unless they are the first or last word. For example: The Lord of the Rings. Notice "of" and "the" (in the middle) are lowercase, but "The" at the beginning is capitalized.

⚠️ SHSAT Trap Alert

The SHSAT loves to test whether you capitalize seasons. Remember: seasons are NOT capitalized (winter, spring, summer, fall). But days of the week and months always are (Monday, September).

Decision Flowchart — Should I Capitalize?

When you hit a capitalization question on the SHSAT, you need a quick mental checklist. The flowchart below walks you through the exact questions to ask yourself. Start at the top and follow the arrows.

Use this flowchart as a mental checklist on the SHSAT. Start at the top and work down. If you answer YES at any step, capitalize the word. If you reach the bottom, keep it lowercase.

Bookmark this flowchart in your mind. On test day, you won't have a chart in front of you, but running through these questions silently takes only a few seconds. The most common SHSAT error involves capitalizing a common noun that looks important (like "mayor" or "ocean") when it isn't part of a specific name.

Tricky Categories That Often Appear on the SHSAT

Category	Capitalize ✓	Do NOT Capitalize ✗
Seasons	(only at the start of a sentence)	winter, summer, fall, spring
School subjects	English, Spanish, French (languages)	math, science, history (general)
Directions	the South (region), the East Coast	Go south on Main Street (direction)
Family words	"I asked Mom for help." (used as name)	"I asked my mom for help."

Worked Example — SHSAT-Style Passage Edit

Let's walk through a sample SHSAT passage just like you'd see on test day. Read the sentence, spot the error, and follow along with the steps to find the fix.

📝 SAMPLE SENTENCE

"Last Summer, mayor Johnson announced that the city would build a new park on atlantic avenue."

Finding and Fixing Capitalization Errors

Step 1 — Read the Sentence CarefullyRead the entire sentence before looking for errors. Get a sense of what it's about: A mayor announced a new park on a certain avenue.

Step 2 — Check Each Capitalized WordLook at every word that starts with a capital letter. "Last" is the first word of the sentence — that's correct. "Summer" has a capital S. Is summer a proper noun? No — seasons are not capitalized. This is an error.

Error found: "Summer" → "summer"

Step 3 — Check Titles Before NamesThe word "mayor" comes directly before a person's name ("Johnson"). When a title appears right before a name, it should be capitalized.

Error found: "mayor Johnson" → "Mayor Johnson"

Step 4 — Check for Missing Capitals on Proper Nouns"atlantic avenue" is the name of a specific street. Both words are part of the proper name, so both need capitals.

Error found: "atlantic avenue" → "Atlantic Avenue"

Step 5 — Write the Corrected SentencePut all the fixes together and reread to make sure everything sounds right.

"Last summer, Mayor Johnson announced that the city would build a new park on Atlantic Avenue."

💡 STRATEGY TIP

On the SHSAT, always check every capitalized word in the underlined portion and every lowercase word that might need a capital. Errors can go both ways — an extra capital or a missing capital. Scan in both directions.

SECTION 7

Common Mistakes & How to Avoid Them

Even strong writers make capitalization mistakes. Knowing the most common traps helps you avoid them. The table below shows errors that appear again and again on the SHSAT.

Six of the Most Frequent SHSAT Capitalization Traps

Common Mistake	Incorrect Example	Correct Version
Capitalizing seasons	We went skiing last Winter.	We went skiing last winter.
Capitalizing a title used alone	The President signed the bill.	The president signed the bill.
Forgetting to capitalize a title before a name	We met captain Rodriguez.	We met Captain Rodriguez.
Capitalizing compass directions	Drive North on the highway.	Drive north on the highway.
Lowercasing a region name	She grew up in the south.	She grew up in the South.
Capitalizing general school subjects	I love Math and Science.	I love math and science.

✦ KEY TAKEAWAY

Think of capitalization like a spotlight on a stage. The spotlight only shines on the star of the show — the specific name. If the word is just part of the background (a general noun), it stays in the dark. "The South" is a spotlight on a region with its own identity. "Drive south" is just a direction — no spotlight needed.

SECTION 8

Beyond the Basics — Titles of Works & Tricky Cases

Once you've mastered proper nouns and personal titles, the next level is learning how to capitalize titles of works like books, movies, and articles. The SHSAT may also test a few tricky edge cases.

Rules for Capitalizing Titles of Works

Rule	Example
Capitalize the first and last word of a title	A Wrinkle in Time
Capitalize all nouns, verbs, adjectives, and adverbs	Harry Potter and the Chamber of Secrets
Keep short prepositions lowercase (in, of, to, for, at)	Lord of the Flies
Keep short conjunctions lowercase (and, but, or)	Romeo and Juliet
Keep articles lowercase unless first or last word (a, an, the)	The Catcher in the Rye

Tricky Edge Cases

Here are a few situations that trip up even good test-takers. Family words: Capitalize "Mom" and "Dad" when they replace a name: "I asked Mom for help." But keep them lowercase when a possessive word like "my" comes before them: "I asked my mom for help." The quick test is: could you swap the family word for the person's actual name? If yes, capitalize it.

Brand names: The brand name is capitalized, but the general product is not: "Nike sneakers" (not "Nike Sneakers"). Course names: A specific course title is capitalized: "Algebra 1". But a general subject is not: "I like algebra." The exception is languages, which are always capitalized because they come from proper nouns (English, French, Spanish).

🔭 LOOKING AHEAD

In high school, you'll encounter more complex capitalization rules — for example, in research papers (MLA or APA style). Those styles have slightly different title rules. For now, master the core rules in this lesson, and the advanced rules will be easy later.

SECTION 9

Practice Problems

Try these five problems on your own before reading the answers. They go from easier to harder, just like the real SHSAT.

PROBLEM 1 — CONCEPTUAL

Which of the following should NOT be capitalized? A) Atlantic Ocean B) Thanksgiving C) Winter D) Dr. Patel

PROBLEM 2 — BASIC

Choose the correctly capitalized sentence: A) My Uncle lives on Elm street in Brooklyn. B) My uncle lives on Elm Street in Brooklyn. C) My uncle lives on Elm Street in brooklyn. D) My Uncle lives on elm street in Brooklyn.

PROBLEM 3 — INTERMEDIATE

Read this sentence and identify the capitalization error: "On tuesday, the Principal of Lincoln middle school announced a new Spanish class." Which words need to be fixed, and how?

PROBLEM 4 — APPLIED

You are editing a classmate's essay. Fix all capitalization errors in this passage: "Last Spring, professor Chen taught a History class at columbia university. She said that the american revolution changed the way people in the North and the south thought about freedom. In Summer, she plans to write a book called the price of liberty."

PROBLEM 5 — CRITICAL THINKING

Explain why the word "earth" is sometimes capitalized and sometimes not. Write the rule, and then create two sentences — one where "earth" is capitalized and one where it is not.

SUMMARY

Lesson Summary

Capitalization on the SHSAT comes down to one core idea: proper nouns (specific names of people, places, organizations, languages, holidays, historical events, days, and months) are always capitalized, while common nouns (general words) stay lowercase. Capitalize a title before a person's name (Mayor Adams), but keep it lowercase when it stands alone (the mayor). Seasons are never capitalized, and general school subjects like math and history stay lowercase (but languages like English are always capitalized).

For titles of works (books, movies, songs), capitalize the first word, last word, and all major words — leave short words like a, an, the, in, of, and lowercase unless they open or close the title. Watch for compass directions: capitalize them only when they name a region (the South), not when they give a direction (drive south). Use the decision flowchart from this lesson as your mental checklist on test day, and you'll catch every capitalization error the SHSAT throws at you.
