“Thankfull” is incorrect.
In this article, you will learn the difference in very easy English with examples, tips, and simple explanations.

- ❌ Thankfull = wrong spelling

Use thankful in all writing situations.
Why Do People Get Confused?
People get confused because many English words end with -full, such as:
- beautiful
- careful
- helpful
- useful
Because of these words, some learners think thankful should also end with -full.
But English spelling is not always perfectly regular. Some words follow different patterns. The correct word is simply thankful, with only one “l” at the end.
Simple Background of the Word
The word thankful comes from the word thank.
- Thank = to show gratitude or appreciation
- Thankful = feeling happy and grateful because of something good
The ending -ful is used in many English adjectives.
Examples:
- careful
- hopeful
- peaceful
- thankful
The ending -ful usually means:
“full of” a feeling or quality
So:
- thankful = full of thanks or gratitude
Even though it sounds like “full,” the spelling in adjectives is usually just -ful with one l.
The Difference Between Thankful and Thankfull
Thankful
Thankful is the correct English word.
It means:
- feeling grateful
- appreciating kindness, help, or good things
Examples:
- I am thankful for my family.
- She felt thankful after receiving help.
- We are thankful for your support.
Thankfull
Thankfull is not a standard English word.
It is only a spelling mistake.
People sometimes accidentally add an extra “l” because they are thinking about the word full.
Incorrect Examples:
- ❌ I am thankfull for everything.
- ❌ She was very thankfull.
These should always be written as:
- ✅ I am thankful for everything.
- ✅ She was very thankful.
