Quick answer: The correct spelling is truly, as “truely” is a common misspelling that is never correct in standard English. When forming the adverb from the adjective “true,” you must drop the final “e” before adding the suffix “-ly”.
If you have ever paused mid-sentence while drafting an important email, polishing your resume, or writing a heartfelt card, wondering whether to write “truly” or “truely,” you are far from alone. This specific spelling confusion ranks among the most frequent adverb errors I see in my years as a professional copy editor.
The confusion stems from a simple but deeply misleading pattern in English spelling. Many adjectives ending in “e” comfortably keep that “e” when transforming into adverbs, but “true” is a notable, stubborn exception.
Understanding the exact grammatical rule behind this specific word will permanently eliminate this doubt from your writing toolkit. Mastering this distinction not only improves your writing but also protects your professional credibility. Seemingly minor typos can inadvertently undermine the authority of your message.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| truly | The correct, standard adverb form of the adjective “true.” It is used to mean genuinely, sincerely, accurately, or faithfully. You must drop the “e” from “true” before adding the suffix “-ly”. | I am truly grateful for your prompt and detailed response to my inquiry. |
| truely | An incorrect, non-standard misspelling. It is not a recognized variant and should never be used in formal writing, casual communication, or professional documents. | (Incorrect) I am truely grateful for your prompt and detailed response. |
When to use truly
You should use “truly” whenever you need an adverb to modify a verb, an adjective, or another adverb, indicating that something is genuine, sincere, or accurate. The grammatical rule at play here is highly specific and consistent. When an adjective ends in a consonant followed by “ue” (such as “true” or “due”), standard English convention strictly dictates that you drop the “e” before adding a vowel suffix like “-ly”.
As a veteran copy editor, I see this error constantly in high-stakes documents where precision and attention to detail are absolutely paramount. A single misspelling can distract the reader and subtly damage your credibility. Below are three concrete, real-world examples of this mistake and exactly how to fix them in your own writing:
- Professional Email Communication:
- Error: “I truely appreciate the time you took to review the Q3 financial report and provide such actionable feedback.”
- Fix: “I truly appreciate the time you took to review the Q3 financial report and provide such actionable feedback.”
- Resume or Cover Letter Profiles:
- Error: “A truely dedicated project manager with a proven, five-year track record of improving customer satisfaction metrics across global teams.”
- Fix: “A truly dedicated project manager with a proven, five-year track record of improving customer satisfaction metrics across global teams.”
- Casual Text Message or Social Media:
- Error: “That was a truely amazing concert last night, the energy was incredible and we have to go again!”
- Fix: “That was a truly amazing concert last night, the energy was incredible and we have to go again!”
Using the correct spelling signals meticulous attention to detail. In a highly competitive job market, automated applicant tracking systems and human recruiters alike notice polish. A misspelling like “truely” on a resume can inadvertently suggest a lack of thorough proofreading, whereas “truly” projects competence, care, and linguistic mastery.
When to use truely
The short, definitive, and absolute answer is that you should never use “truely”. It is not an alternative spelling, it is not a stylistic choice, and it is not an accepted variant in any modern, reputable dictionary.
The misspelling “truely” persists primarily because writers unconsciously overapply a different, much more common English spelling rule. For a vast majority of adjectives ending in “e” (such as “complete,” “absolute,” “polite,” or “extreme”), the “e” is comfortably retained when adding “-ly” to form “completely,” “absolutely,” “politely,” or “extremely.” Your brain recognizes this dominant pattern and incorrectly applies it to “true.”
However, linguistics and established style guides are crystal clear on this point. As detailed in Grammarly’s guide on commonly confused words, “truely” is universally flagged as a misspelling that must be corrected to “truly” in absolutely all contexts.
Furthermore, conforming to established standard usage is the very definition of being correct in written language. Because “truely” appears in no reputable dictionary, using it immediately marks the text as unpolished and amateurish. Whether you are drafting a wedding toast, writing a LinkedIn bio, or sending a quick Slack message to a colleague, “truely” has no place in your vocabulary. Relying on phonetic spelling is a trap, as English orthography is famously inconsistent with phonetic expectations.
How to remember the difference
To permanently banish “truely” from your writing, you need a reliable, foolproof mental shortcut. Relying on gut feeling is inherently risky because the “complete/completely” pattern is so deeply ingrained in your cognitive processing. Instead, use these editor-approved memory tricks:
The “Due/Duly” Parallel Rule Think of the word “true” alongside the word “due.” Both words share the exact same ending: “-ue.” When you make “due” into an adverb, you do not write “duely”; you write “duly.” The exact same mechanical, grammatical rule applies to “true.” If you can firmly remember that “due” becomes “duly,” you will automatically and correctly remember that “true” becomes “truly.”
The “Make Room” Visualization Another highly effective trick is to visualize the word “true” physically making room for the suffix. Imagine the silent “e” at the end of “true” politely stepping aside to let the “l” and “y” take their proper place. The word “true” is already complete and valid on its own; it does not need to hold onto the “e” to prove its legitimacy when a suffix is attached.
Editor-Level Proofreading Insight: When proofreading your own work, do not just read for flow or rhythm; read specifically for the “-ue” to “-uly” transition. Our brains are wired to autocorrect misspellings silently as we read, which is why you might read “truely” five times in a row and not notice the error. To catch it, read your sentences backward, word by word, starting from the very end. This simple technique disrupts your brain’s predictive text engine and forces you to look at the actual, isolated spelling of each individual word, making “truely” stand out like a sore thumb.
Common mistakes and exceptions
Writers often wonder if there are any hidden exceptions, regional differences, or niche contexts where “truely” might suddenly become acceptable. Let us address the most common edge cases and misconceptions directly to clear up any lingering doubt.
US vs. UK English Differences A frequent question is whether “truely” is the preferred, accepted British spelling, while “truly” is strictly American. This is a complete myth. There is absolutely no difference between American, British, Canadian, or Australian English on this matter. The spelling rule remains identical across all major global variants of the language. You will not find “truely” in the Oxford English Dictionary, Merriam-Webster, or the Cambridge Dictionary.
The “Yours Truly” Sign-off The formal letter sign-off “Yours truly” is a frequent casualty of this specific spelling error. Because it is a set, traditional phrase used at the end of formal correspondence, writers sometimes second-guess it and mistakenly type “Yours truely.”
Remember that this phrase is simply an extension of the adverb. It historically means “I am yours in a true manner.” Therefore, the exact same rule applies: drop the “e.” Always write “Yours truly,” and never “Yours truely.”
Related Words: Truthful vs. Truly Another common stumble occurs when writers try to use a synonym to avoid the word altogether, but end up creating a brand new error. The adjective “truthful” becomes the adverb “truthfully.” Notice that “truthful” keeps the “l” and adds “ly” because it ends in “ful,” not “ue.” Do not mix these distinct grammatical paths up. You can be “truthful,” and you can act “truthfully,” but you are always “truly” sorry.
The “Un-” Prefix Adding a negative prefix does not change the core spelling rule of the base word. The opposite of truly is “untruly.” Even with the prefix attached, the base word “true” has already lost its “e” during the adverb formation. You will never write “untruely.” The rule remains anchored to the root transformation.
Frequently Asked Questions
Is truely ever correct in any dictionary? No, “truely” is not listed as a valid word in any major, reputable English dictionary, including Merriam-Webster, Oxford, or Cambridge. It is universally classified by linguists and editors as a misspelling.
Why do so many people spell it truely? People misspell it as “truely” because they incorrectly apply the standard rule for words like “complete” (which becomes “completely”). They assume the “e” should be retained, not realizing that words ending in “-ue” follow a different, specific dropping pattern.
Does the rule change if I am writing in British English? No, the rule does not change at all. “Truly” is the only accepted spelling in British English, American English, and all other major regional variants. “Truely” is always considered incorrect regardless of geography.
How do I form the adverb for other words ending in “ue”? The grammatical rule is highly consistent: drop the “e” before adding “-ly.” For example, “due” becomes “duly,” and “continuous” becomes “continuously.” This pattern holds firm across standard English grammar without exception.
