Capitalization Rules

Proper Names Versus General Categories

Capitals mark beginnings and proper names, not importance. Capitalize official course names but not general fields (Introduction to Biology; biology), named regions but not directions (the Pacific Northwest; drive northwest), and a title when it functions as part of a name (Professor Alvarez) rather than as a general description (the professor). Title-capitalization styles differ on short words, so follow the assigned style.

Worked example: On monday, professor Chen teaches history in the West wing becomes On Monday, Professor Chen teaches history in the west wing.

Why This Matters: Use language structure and context to choose clear, accurate sentences in academic and everyday writing.

What You Need to Know

Capital letters are used for specific types of words. Incorrect capitalization can make writing look unprofessional or even change meaning.

🧠 Memory Trick

Capitalize PINTS:

• Proper nouns (specific names)
• I (always capitalize!)
• Nations, nationalities
• Titles (when with name)
• Start of sentence

Capitalization Rules

1. First Word of a Sentence

Always capitalize the first word:

• The patient arrived at 9 AM.
• After the procedure, rest is recommended.

2. Proper Nouns (Specific Names)

3. Titles with Names

Capitalize when used WITH a name, not when standing alone:

4. Product Names and Common Nouns

Capitalize a stated brand or other proper name; use lowercase for an ordinary product category unless it begins a sentence. If a passage identifies Northstar as a notebook brand, write “a Northstar notebook.” Brand knowledge should be supplied, not assumed.

5. Academic Subjects

• Capitalize specific course names: English 101, Anatomy and Physiology
• Don't capitalize general subjects: math, science, nursing (unless part of a title)
• Always capitalize languages: English, Spanish, French

6. Directions

• Capitalize when referring to regions: the South, the Midwest
• Don't capitalize when indicating direction: Go south on Main Street

✏️ Worked Examples

Example 1: Proper Nouns

WRONG: "The Patient was admitted to saint mary's hospital."

Step 1 — Find every word that should be capitalized and check them one by one.

Step 2 — "The Patient" — is patient a proper noun? No. A patient is a common noun — it's a general category of person, not a specific person's name. Lowercase: patient.

Step 3 — "saint mary's hospital" — is this a specific place? Yes! Saint Mary's Hospital is the name of a particular hospital. Specific place names are proper nouns → capitalize every significant word: Saint Mary's Hospital.

Step 4 — Put it together.

CORRECT: "The patient was admitted to Saint Mary's Hospital."

Why this matters: In nursing documentation, writing "saint mary's hospital" looks careless. The official name of the facility is a proper noun and must be capitalized.

Example 2: Titles

WRONG: "doctor Smith consulted with the Nurse."

Step 1 — Look at "doctor Smith." Is "doctor" being used with a specific person's name? Yes — it comes right before "Smith." Title + name = capitalize. → Doctor Smith (or abbreviated: Dr. Smith)

Step 2 — Look at "the Nurse." Is "nurse" being used with a specific name? No — it's just "the nurse," a general reference. Title without a name = lowercase. → the nurse

Step 3 — Put it together.

CORRECT: "Dr. Smith consulted with the nurse."

The rule in plain English: Think of it like this — when you're using "doctor" or "nurse" as part of a person's official title right before their name, it acts like part of their name (capitalize it). When you're just referring to the profession generally, it's not a name — it's a job description (lowercase).

Example 3: Product name and category

Sentence: “Mara bought a northstar Notebook.” The passage identifies Northstar as the brand. Revise to “Mara bought a Northstar notebook.” Capitalize the proper name, not the ordinary product category.

Example 4: Directions vs. Regions

These look identical in a sentence but mean different things:

"The hospital is in the South." → South is capitalized here because it refers to a geographic region of the country (the Southern United States). Region names are proper nouns.

"Walk south to find the cafeteria." → south is lowercase here because it's a direction — a compass direction telling someone which way to go. Direction words are not proper nouns.

The test: Can you replace the word with a region name? "Walk the Southern United States to find the cafeteria" — that makes no sense. → It's a direction → lowercase. "The hospital is in the South" — yes, this refers to a place → capitalize.

Common Capitalization Errors

💡 Pro Tips

• Specific = capital; General = lowercase
• Supplied brand names are proper names; ordinary product categories are lowercase
• Titles only capitalize WITH a name ("Dr. Smith" but "the doctor")
• Days and months always capitalized; seasons are not
• On the TEAS: Watch for incorrect capitalization of titles and common nouns

⚠️ Common Mistakes to Avoid

• Capitalizing professions: "Nurse" ✗ → "nurse" ✓ (unless with name)
• Common product categories: “a Notebook” ✗ → “a notebook” ✓
• Random capitalization: "The Patient is in Stable Condition" ✗
• Missing capitals on proper nouns: "memorial hospital" ✗

Quick Reference

Always Capitalize

• First word of sentence
• Proper nouns (specific names)
• Titles with names
• Days, months, holidays
• Proper product/brand names
• Languages
• The pronoun "I"

Usually Lowercase Unless at Sentence Start or in a Proper Name

• Common nouns (the hospital, a nurse)
• General subjects (math, science)
• Seasons (spring, winter)
• Ordinary product categories
• Directions (go north)
• Titles without names (the president)
