When I was editing student essays last week, I saw “truely” three times on a single page. All three times, the student had written something important — advice to a friend, a sincere compliment, a heartfelt statement. And in all three cases, the misspelling made the writing look careless, even though the feeling behind it was genuine.
The good news is simple: there is only one correct spelling. “Truly” is the word. “Truely” is a mistake. You’ll shows you why this spelling rule exists, three memory tricks that actually work, and the exact places where this mistake shows up in real writing.
Key Takeaways
- Only “truly” is correct — “truely” is a common misspelling with no place in modern English.
- Why the mistake happens: The root word “true” ends in e, so learners add another e when making it an adverb — but that’s wrong.
- Memory hook: When a word ends in a silent e, drop it before adding -ly. True → trul + y = truly.
- Same rule applies to: wise → wisely (not wiseley), base → basely (not baseley).
- Yours truly: A formal closing in letters and emails. Always spelled “yours truly ” — never “truely.”
Understanding “Truly”
Definition and Part of Speech
Truly is an adverb — a word that describes how an action happens or modifies an adjective. It means “in a truthful way,” “genuinely,” “authentically,” or “in accordance with fact.” When you say someone “truly believes” something, you’re emphasizing that the belief is sincere and real, not pretend.
Example 1: She truly loves her job — you can see it every day.
Example 2: I truly appreciate your support during this difficult time.
Example 3: The evidence truly supports the conclusion.
Example 4: That was a truly unforgettable experience.
Example 5: He truly gave his best effort in the competition.
Common Uses of “Truly”
“Truly” appears in three main contexts: (1) to emphasize sincerity (“I truly care”), (2) to express agreement with reality (“The painting is truly beautiful”), and (3) in the formal closing “Yours truly” in letters and emails.
In formal writing, “truly” is often paired with phrases like “truly believe,” “truly understand,” or “truly grateful.” In less formal contexts, native speakers sometimes use it for emphasis, as in “That is truly amazing!”
Pronunciation note: “Truly” is pronounced “TROO-lee” (rhymes with “pooley”), not “TROO-el-ee.” The ly ending is said as a single syllable, not two.
Why “Truely” Is Incorrect
The mistake happens because learners see the word “true” (which ends in a silent e) and think they should keep that e when they add -ly. But English spelling has a rule for this: when a word ends in a silent e, you usually drop the e before adding a suffix that starts with a vowel (like -ly, -ing, or -able).
Example pattern:
- true + ly = truly (drop the e) ✓
- base + ly = basely (drop the e) ✓
- wise + ly = wisely (drop the e) ✓
- use + able = usable (drop the e) ✓
All of these follow the same rule: drop the silent e, then add the suffix. “Truely” violates this rule by keeping the e, which is why it’s wrong.
The Rule: Silent E → Drop Before -ly. If a word ends in a silent e, drop it before adding -ly to form an adverb. True → trul-y = truly. That’s it.
Historical Context
Interestingly, “truely” was actually an acceptable spelling in English until the 19th century. During the 1700s and 1800s, English spelling was being standardized, and writers had to choose between competing spellings. The spelling “truly” (without the extra e) eventually won out and became the standard. Today, any spelling authority — Merriam-Webster, Oxford, Cambridge — lists only “truly” as correct.
| Word | Root | Rule applied | Correct form | Incorrect form |
|---|---|---|---|---|
| True → Adverb | true (ends in silent e) | Drop e before -ly | truly ✓ | truely ✗ |
| Base → Adverb | base (ends in silent e) | Drop e before -ly | basely ✓ | baseley ✗ |
| Wise → Adverb | wise (ends in silent e) | Drop e before -ly | wisely ✓ | wiseley ✗ |
| Sole → Adverb | sole (ends in silent e) | Drop e before -ly | solely ✓ | soleley ✗ |
Pronunciation and Writing
Native speakers pronounce “truly” the same way every time: “TROO-lee” with the stress on the first syllable. The word has two syllables, not three. This is important because many learners try to pronounce “truely” (adding an extra syllable), which reinforces the misspelling.
When you write, remember: the pronunciation is “TROO-lee,” which means the spelling should show just two syllables — t-r-u-l-y — not three.
Common Contexts for “Truly”
| Context | Example sentence | Meaning |
|---|---|---|
| Emphasizing sincerity | “I truly believe you can do this.” | My belief is genuine and sincere |
| Confirming reality | “That is a truly beautiful painting.” | It is genuinely beautiful, not exaggerated |
| Expressing agreement | “You are truly the best.” | This is a real, honest statement |
| Formal letter closing | “Yours truly, James” | A polite, traditional way to sign off |
| Starting a serious comment | “Truly, I had no idea.” | Used as an interjection for emphasis |
Common Spelling Mistakes
✗ Incorrect: I truely appreciate your help.
✓ Correct: I truly appreciate your help.
Why: “Truly” is the only correct spelling of this adverb. The silent e is dropped when adding -ly.
✗ Incorrect: He said, “Yours truely, John.”
✓ Correct: He said, “Yours truly, John.”
Why: In the formal closing “Yours truly,” the spelling is always truly, never truely.
✗ Incorrect: The evidence truely supports the hypothesis.
✓ Correct: The evidence truly supports the hypothesis.
Why: When using “truly” in formal or academic writing, use only the correct spelling. Misspelling it weakens the credibility of your writing.
The “Yours Truly” Phrase
“Yours truly” is a traditional, formal way to close a letter or email. It appears in business correspondence, formal invitations, and official communications. The phrase literally means “yours sincerely” or “yours faithfully.”
Example: “Thank you again for your consideration. Yours truly, Ms. Rodriguez.”
In modern emails, “Yours truly” sounds quite formal and is less common than it was fifty years ago. Today, many writers use “Best regards,” “Sincerely,” or just “Thanks” instead. But when you do use “Yours truly,” make sure it’s spelled correctly — never “Yours truely.”
Other Words with the Same Rule
If you understand the rule for “truly,” you’ll get these right too:
- wise → wisely (not wiseley)
- base → basely (not baseley)
- sole → solely (not soleley)
- nice → nicely (not niceley)
- safe → safely (not safeley)
- late → lately (not lateley)
The Pattern: Word ending in silent e + -ly = drop the e, add -ly. This rule applies to hundreds of adverbs in English.
Sample Dialogue
Sam: I’ve written this email to my boss, but I want to check something. Is it “Yours truely” or “Yours truly”?
Alex: Definitely “truly” — T-R-U-L-Y. Only one E at the end.
Sam: But the word is “true,” which has an E. Why do we drop it?
Alex: Because of the silent-E rule. When you add -ly to words ending in a silent E, you drop the E first. True becomes truly, just like wise becomes wisely.
Sam: That makes sense! So it’s the same pattern everywhere?
Alex: Exactly. Once you know the rule, you’ll never misspell it again.

Frequently Asked Questions
Is “truely” ever correct?
No. “Truely” is never correct in modern English. It was an acceptable variant spelling until the 19th century, but today all major dictionaries recognize only “truly” as the correct spelling. Always use “truly.”
Why is the E dropped in “truly”?
It follows the silent-E rule: when a word ends in a silent E, drop it before adding a suffix that begins with a vowel (like -ly, -ing, -able). True + ly becomes truly, not truely.
What about other words with the same root?
The same rule applies to many words ending in silent E: wise → wisely, base → basely, sole → solely, nice → nicely, safe → safely. Once you know the rule, you can spell them all correctly.
How do I remember “Yours truly”?
Remember that “truly” is always spelled T-R-U-L-Y in the phrase “Yours truly.” Think of it as a formal closing in letters where you’re saying “sincerely yours.” Since it’s formal, use the correct spelling.
Do native speakers ever misspell “truly”?
Yes — especially when typing fast or when autocorrect doesn’t catch it. But in professional and academic writing, this misspelling stands out and makes the writer look careless. Always proofread this word carefully.
Are there memory tricks to remember the correct spelling?
Yes. Remember “TROO-lee” (the pronunciation) is only two syllables. The spelling should match: T-R-U-L-Y (not T-R-U-E-L-Y). Or use the rule: silent E → drop it before -ly.
