Smooth is the standard spelling in modern English. It can be used as an adjective and a verb, as in “The surface is smooth” and “Please smooth the paper.” Smoothe has appeared as an older or alternative form, especially as a verb, but it is uncommon in contemporary standard English. For everyday, academic, professional, and edited writing, use smooth.
What Is the Difference Between Smoothe and Smooth?
The main difference is not meaning but modern usage and spelling. Smooth is the normal modern English form. It can describe something that is even, soft, polished, flowing, or free from difficulty, and it can also function as a verb meaning “to make something smooth” or “to make something more even or orderly.”
Smoothe is a much less common form that has historical evidence as an alternative spelling of smooth, particularly as a verb. It may appear in older texts or unusual sources, but it is not the form modern writers normally choose.
So, if you are writing an email, essay, article, report, school assignment, or social media post, the practical choice is simple: write smooth, not smoothe.
Why It Matters
A single extra letter can make a familiar word look incorrect. Writing smoothe in a modern sentence may cause readers to pause because the spelling does not match the standard form they expect.
This matters particularly in professional and academic writing. Compare these sentences:
- Correct and standard: We need to smooth the transition.
- Unusual in modern standard writing: We need to smoothe the transition.
The meaning is understandable in the second sentence, but smooth is the established modern choice. Using the standard form removes unnecessary doubt and keeps the writing clear.
The Core Rule
Use “smooth” as the standard modern spelling.
Do not assume that smoothe is the verb form and smooth is only the adjective. Modern English does not require that distinction.
Use:
smooth → adjective
The table has a smooth surface.
smooth → verb
Please smooth the paper.
smoothly → adverb
The meeting went smoothly.
smoothed → past tense/past participle
She smoothed the fabric.
The easiest rule is: keep the base word as “smooth.”
How to Use Smooth
Smooth is a flexible word with several common meanings. It can describe physical texture, movement, sound, behavior, writing, processes, or experiences.
Smooth as an Adjective
As an adjective, smooth describes something that is even, not rough, or free from noticeable bumps or irregularities.
For example:
- The stone feels smooth.
- The cream leaves your skin smooth.
- The table has a smooth surface.
- She has smooth hair.
It can also describe something that happens easily or without problems:
The hiring process was smooth.
Smooth as a Verb
Smooth can also be a verb. It means to make something smooth, even, flat, or more orderly.
- Smooth the paper before folding it.
- She smoothed her dress.
- He smoothed the surface with his hand.
- We need to smooth the transition between the two sections.
Notice that the verb is still spelled smooth. You do not need to add an extra e.
Smoothly as an Adverb
When you want to describe how an action happens, the usual adverb is smoothly.
For example:
- The machine is running smoothly.
- The presentation went smoothly.
- The project moved smoothly from one stage to another.
Do not create the spelling smoothely by adding an extra e. The standard adverb is smoothly.

Why Do People Write Smoothe?
The Extra “e” Looks Plausible
One major reason is that English contains many words ending in a silent e, such as breathe, bathe, clothe, and soothe. Because smooth has a similar sound pattern, writers may assume that smoothe follows the same spelling pattern.
Confusion With Soothe
Smooth and soothe look similar, and both contain oo. However, they are different words with different meanings.
Smooth can mean to make something even or to make a process easier.
Soothe means to calm, comfort, or reduce irritation or pain.
For example:
- She used a cloth to smooth the surface.
- The music helped soothe the baby.
Overgeneralizing English Spelling Patterns
English spelling contains many patterns, but they do not always apply to every similar-looking word. A writer may think that adding e turns an adjective into a verb, but that is not a reliable general rule in English.
Seeing Smoothe in Older Texts
The confusion is also understandable because smoothe is not entirely invented. Historical sources record it as an alternative form of smooth, and it can still appear in older or unusual texts. That does not make it the normal modern spelling.
Spellcheck and Online Usage
Seeing a spelling repeatedly online does not necessarily mean it is the standard form. User-generated content, old quotations, names, product branding, and individual spelling mistakes can all expose readers to uncommon forms.
Common Mistakes Checklist
- Adding an extra e: Write smooth, not smoothe, in ordinary modern writing.
- Using smoothe as the verb: The standard verb is smooth.
- Writing smoothely: The standard adverb is smoothly.
- Confusing smooth and soothe: Smooth relates to evenness or ease; soothe relates to calming or comforting.
- Assuming historical use means modern standard use: Older spellings can survive in historical sources without being the normal choice today.
- Changing the base spelling unnecessarily: Keep the word family centered on smooth: smooth, smoother, smoothest, smoothly, smoothed, smoothing.
Smoothe vs Smooth in Real English
Smooth — Standard and Natural
Smooth is the normal word used in contemporary English. It works naturally as an adjective and verb and appears across everyday conversation, business writing, academic work, product descriptions, and creative writing. Sentences such as “The surface is smooth,” “Smooth the paper,” and “The process went smoothly” are ordinary modern English.
Smoothe — Historically Attested but Unusual Today
Smoothe has existed as an alternative form, particularly as a verb, so calling it a completely invented spelling would be too absolute. However, it is not the normal modern form. In contemporary standard writing, using smooth avoids an archaic, unusual, or potentially mistaken appearance.
Smoothly — The Natural Adverb
When smooth describes how an action happens, smoothly is the standard adverb. For example, “The presentation went smoothly” means that it happened without significant problems or interruptions. Using smoothely adds an unnecessary letter and does not follow the standard spelling of the word family.
American vs. British English
There is no meaningful American-versus-British spelling difference for the ordinary modern use of smooth. American and British English both use smooth as the standard spelling.
The practical rule is therefore the same for both varieties: use smooth in modern standard writing rather than smoothe.
Formal vs. Informal Usage
Smooth is appropriate in both formal and informal English. There is no special formal spelling that requires smoothe.
Examples include:
- Informal: “The whole thing went smooth.”
- Standard written English: “The whole thing went smoothly.”
- Formal: “The revised procedure should ensure a smooth transition.”
The first example can occur in casual speech, but smoothly is the conventional adverb in careful standard writing. The spelling smoothe is not a formal alternative to smooth.

- Smooth — base word
