Does Laboratory Need A Capital Letter?

Follow these four steps to correct capitalization of "Laboratory."

1. Review the full sentence. If the sentence reads “The laboratory published results,” keep laboratory lowercase.
2. Identify proper-name strings. If the sentence is “The Beckman Laser Institute Laboratory published results,” capitalize both “Institute” and “Laboratory.”
3. Use find-and-replace. Press Ctrl+Shift+F in Microsoft Word or Cmd+Shift+F on a Mac to search for “ Laboratory ” (with spaces). Replace only instances that follow a comma or start a sentence with “ Laboratory ”—capitalized.
4. Inspect headings and titles. In a table of contents or a caption like “Figure 3: Laboratory Equipment,” capitalize Laboratory.

If capitalization remains incorrect, check the organization’s style guide or consult the editor.

• Verify the organization’s style guide. Some institutions, like the NIH, lowercase “laboratory” in headings unless it is part of a trademarked name.
• Contact the editor or publisher. If your document is destined for an AMA-style journal, confirm whether their section headings use title case or sentence case.

Prevent future capitalization errors by using autocorrect, style-checking tools, or institutional glossaries.

• Set up a custom autocorrect in Microsoft Word: replace “ lab ” with “ laboratory ” and keep it lowercase, or add the full proper-name string to your institution’s glossary.
• Use a style-checking plug-in such as PerfectIt or Grammarly. Both updated their laboratory-specific rules as of 2026.
• Before finalizing your document, run it through Grammarly and set the dialect to “U.S. English” to catch any remaining errors.

Capitalize “Laboratory” only at the start of a sentence or in a proper name; otherwise, keep it lowercase.

In formal and technical writing, laboratory is usually a common noun. That means it stays lowercase unless it begins a sentence or shows up in an official proper name like “MIT.nano Laboratory.” As of 2026, this rule matches what you’ll find in the Associated Press Stylebook and the Chicago Manual of Style.

Use lowercase for “laboratory” unless it starts a sentence or is part of a proper name.

In formal and technical writing, laboratory is generally a common noun—so it stays lowercase. The exceptions? When it kicks off a sentence or shows up in an official proper name like “MIT.nano Laboratory.” As of 2026, that’s still the rule in the Associated Press Stylebook and the Chicago Manual of Style.

Follow these four steps to correct capitalization of “laboratory.”

1. Look at the full sentence. If you see “The laboratory published results,” leave laboratory lowercase.
2. Check for proper-name strings. If the sentence reads “The Beckman Laser Institute Laboratory published results,” capitalize both “Institute” and “Laboratory.”
3. Run a find-and-replace. Hit Ctrl+Shift+F in Word or Cmd+Shift+F on a Mac to hunt for “ Laboratory ” (with spaces). Swap only the ones that follow a comma or start a sentence to “ Laboratory ”—capitalized, of course.
4. Inspect headings and titles. In a table of contents or a caption like “Figure 3: Laboratory Equipment,” capitalize Laboratory.

If capitalization issues persist, check the organization’s style guide or consult the editor.

• Check the organization’s style guide. Some places, like the NIH, still lowercase “laboratory” in headings—unless it’s part of a trademarked name.
• Ask the editor or publisher. If your piece is heading to an AMA-style journal, double-check whether their section headings use title case or sentence case.

Prevent future capitalization errors with autocorrect rules, style-checking tools, and style guides.

• Add a custom autocorrect in Word: swap “ lab ” for “ laboratory ” and keep it lowercase, or toss the full proper-name string into your institution’s glossary.
• Try a style-checking plug-in like PerfectIt or Grammarly. Both updated their lab-specific rules as of 2026.
• Before you call it done, run the manuscript through Grammarly and set the dialect to “U.S. English” to catch any stragglers.

You only capitalize degree titles if they're part of the award, like "Bachelor of Science in Computer Science."

For example, you’d write “Bachelor of Science in Computer Science,” but leave “science” lowercase in most other cases. Same goes for course names: “Computer Science 101” needs that capitalization, but plain “science” doesn’t.

Generic subjects like math and chemistry stay lowercase, but specific course names get capitalized.

Here’s the deal: subjects such as math, algebra, geology, and psychology don’t need capitals. Languages like French and Spanish do, though, because they’re proper nouns. When you’re talking about a specific class—say, Math 241 or Chemistry 100—always capitalize it.

School subjects stay lowercase, except for languages and specific course titles.

Names of school subjects like math, algebra, geology, and psychology aren’t capitalized. The exception? Languages (French, English). Course titles, however, always get capitalized—think Algebra 201 or Math 001. Oh, and capitalize titles of people when they’re part of a proper name.

These ten rules cover most capitalization cases you’ll run into.

• Capitalize the first word of every sentence.
• “I” is always capitalized, along with all its contractions.
• Capitalize the first word of a quoted sentence.
• Capitalize a proper noun.
• Capitalize a person’s title when it precedes the name.
• Capitalize the names of days, months, and holidays—but not seasons.
• Capitalize most words in titles.
• Capitalize the first word after a colon, but only if it’s a complete sentence.
• Capitalize proper adjectives (e.g., “Shakespearean” or “Victorian”).
• Capitalize the names of specific places, organizations, and events.

Always capitalize "English" when referring to the language or nationality.

Even online, where casual writing runs rampant, “English” as a language or nationality always gets a capital letter. It’s a proper noun, after all. Casual writers might skip it, but grammatically, it’s required.

Unless it starts a sentence, “medicine” stays lowercase.

Students writing personal statements often trip up here. Outside of sentence starters, “medicine” should stay lowercase. The exception? When it’s part of a journal title or group name—then it gets capitalized.

These eight rules cover most capitalization scenarios.

• Capitalize the first word of a sentence.
• Capitalize names and other proper nouns.
• Avoid capitalizing after a colon (usually).
• Capitalize the first word of a quote (sometimes).
• Capitalize days, months, and holidays, but not seasons.
• Capitalize most words in titles.
• Capitalize proper adjectives.
• Capitalize the names of specific places, organizations, and events.

These six rules handle most capitalization needs.

• Capitalize the first word of a sentence.
• Capitalize names and other proper nouns.
• Avoid capitalizing after a colon (usually).
• Capitalize the first word of a quote (sometimes).
• Capitalize days, months, and holidays, but not seasons.
• Capitalize most words in titles.

People’s names are always proper nouns and need capitalization.

That means John William Smith gets three capital letters—one for each part of the name. It’s not just first names; middle names and last names all get that uppercase treatment.

Capitalization has three main meanings: uppercase letters, business valuation, and stock value.

The term refers to writing in uppercase letters, the total invested in a business, or the total value of a corporation’s stocks and bonds. For example, if a company’s outstanding shares total $100,000, that’s its capitalization.

Don’t capitalize articles or conjunctions unless they’re first or last in a title.

Articles like a, an, and the stay lowercase unless they kick off or wrap up a title. Same goes for coordinating conjunctions (and, or, nor, but, for, yet, so)—they don’t get capitals unless they’re first or last. The word “to” in infinitives follows the same rule.

Capital letters serve four key purposes in writing.

• They distinguish people, places, or related words.
• They mark the beginning of a sentence.
• They highlight titles of books, films, organizations, etc.
• They’re used in abbreviations.

“English teacher” needs a capital “E” because “English” is a language.

Languages always get capitalized, so “English teacher” is correct. Same goes for French teacher, German professor—you get the idea. It’s about the language, not the job title.

The terms “uppercase” and “lowercase” come from old printing press organization.

Back in the day, print shops stored metal type in cases. The less-frequently used capital letters went in an upper case, while the more common lowercase letters sat in a lower case that was easier to reach. Hence the terms we still use today.

Generic drug names like paracetamol stay lowercase.

Drugs and medicines should always use lowercase for their generic names. So you’d write “patients had 500 mg paracetamol” rather than “Paracetamol.” Consistency matters here—pick one format and stick with it.
