Many people search for truly or trully because both spellings look believable at first glance.
Since many English words ending in -ly keep all the letters of their root word, learners often assume that truly should be spelled trully with two L’s.
This confusion appears in school assignments, emails, blogs, business writing, social media posts, and everyday conversations.
The simple answer is that truly is the correct spelling, while trully is a common spelling mistake.
The word truly is an adverb that means genuinely, honestly, really, or sincerely. It is widely used in spoken and written English to emphasize truth, sincerity, or certainty.
This guide explains the correct spelling, pronunciation, grammar, meaning, origin, examples, and common mistakes so you can confidently use truly in any situation.

Pronunciation of Truly and Trully
Both spellings are pronounced the same, which is one reason many people spell the word incorrectly.
Truly
American English
TROO-lee
IPA:
/ˈtruː.li/
British English
TROO-lee
IPA:
/ˈtruː.li/
Trully
Although some people write trully, it has no accepted spelling in English dictionaries. If someone writes trully, they still pronounce it exactly like truly.
Why People Confuse Truly and Trully
Several factors make this one of the most common English spelling mistakes.
The Double-L Rule
Many English words contain two L’s, including:
- Fully
- Carefully
- Skillfully
Because of these examples, learners assume truly should also contain two L’s.
Pronunciation Doesn’t Help
Both spellings sound exactly the same, so pronunciation gives no clue about the correct spelling.
Typing Habits
People often double letters automatically when typing quickly.
Lack of Grammar Knowledge
Many writers don’t know that true follows a special spelling rule when adding -ly.
Easy Trick to Remember Truly or Trully
Here’s a simple memory trick.
The adjective is:
True
When adding -ly, the final E is dropped.
True → Truly
Notice that no extra L is added.
Remember this formula:
True − E + LY = Truly
If you remember this spelling rule, you’ll never write trully again.
The Origin of Truly
The word truly comes from the adjective true, which has been part of English for hundreds of years.
The adjective true means:
- Correct
- Honest
- Faithful
- Genuine
- Accurate
When English forms the adverb, it removes the final E and adds -ly.
True → Truly
This spelling has remained unchanged in both British and American English.
British English vs American English
There is no spelling difference.
| British English | American English |
|---|---|
| Truly | Truly |
| Trully | Incorrect |
Both varieties of English always use truly.

Grammar Rule for Truly
One of the most searched grammar questions is:
Why is it “truly” instead of “trully”?
The answer is based on a standard English spelling rule.
When an adjective ends in -ue, the final E is usually removed before adding -ly.
Examples:
| Adjective | Adverb |
|---|---|
| True | Truly |
| Due | Duly |
Notice that no extra L is added.
This is why trully is always incorrect.

Examples:
- I truly appreciate your kindness.

Always replace trully with truly before publishing your writing.
