If you are choosing between smoothe vs smooth, the practical answer is straightforward: smooth is the normal spelling to use in modern US English.
The extra e in smoothe can look believable, especially because English has many words with silent final letters. But the two forms do not represent two modern words with different meanings.
Smooth works as an adjective and a verb. It can describe an even surface, an easy process, steady movement, or an action that makes something more even or removes difficulties.
Smoothe does have a documented place in dictionaries as an alternative spelling, especially for the verb, but it is not the ordinary contemporary choice.
Quick Answer
Use smooth in normal modern writing.
- Smooth — the standard contemporary spelling; it works as an adjective and a verb.
- Smoothe — a recorded alternative spelling, but uncommon and generally unsuitable for ordinary modern US writing.
For example:
- Correct: The table has a smooth surface.
- Correct: Please smooth the paper before folding it.
- Avoid in ordinary modern writing: Please smoothe the paper.
The important point is that smooth does not need an extra e to work as a verb.
Why People Confuse Them
The spelling smoothe feels logical because English uses final e in several familiar verbs. A writer may unconsciously expect the same pattern here.
There is another source of confusion: the verb smooth has forms such as smooths, smoothed, and smoothing. Seeing smoothes in some dictionaries can also make it seem that the base form must be smoothe. It does not.
The base verb is smooth.
For example:
I smooth the fabric.
She smooths the fabric.
She smoothed the fabric.
She is smoothing the fabric.
So the extra e is not needed to turn the adjective into a verb.
Key Differences At A Glance
| Feature | Smoothe | Smooth |
|---|---|---|
| Modern standard choice | No | Yes |
| Adjective | Alternative/historical form is recorded, but uncommon | Yes |
| Verb | Recorded as an alternative spelling | Yes |
| Normal US-English writing | Generally avoid | Use |
| Pronunciation | No useful modern distinction | /smuːð/ |
The central difference is therefore usage status, not meaning. When smoothe appears, it generally points to the same basic word represented by smooth rather than a separate modern concept.
Meaning and Usage Difference
Smooth has several common uses.
It can describe a physical surface:
The new countertop feels smooth.
It can describe a substance without lumps:
Stir the sauce until it is smooth.
It can describe movement:
The train made a smooth stop.
It can describe an event or process without problems:
The move to the new office was smooth.
It can also work as a verb:
Smooth the wrinkles out of the shirt.
The verb can mean making something physically even, but it can also mean making a process easier. For example, someone might smooth the transition between two stages.
Smoothe does not provide a separate modern meaning that readers need to learn. Collins records it as an alternative spelling of smooth, while other references identify it as historical or archaic. That makes it useful to recognize when encountered, but not normally to choose when writing contemporary US English.
The pronunciation does not create a practical distinction either. Smooth is pronounced /smuːð/ in American English.
Tone, Context, and Formality
In everyday US English, smooth is the natural choice regardless of whether the writing is casual, academic, professional, or technical.
You would write:
The installation process was smooth.
Use sandpaper to smooth the edge.
She gave the presentation a smooth finish.
Smoothe can appear in older material or as an unusual spelling. You may also encounter it in a preserved quotation, name, or other special context. In those cases, recognizing the form is useful.
However, deliberately choosing smoothe in a new sentence can make contemporary readers pause because it is much less familiar.
So the distinction is mainly about standard modern usage versus an uncommon recorded alternative, rather than a difference in tone or meaning.
Which One Should You Use?
Choose smooth in virtually all ordinary modern US-English writing.
Use it in:
- School assignments
- Emails and workplace messages
- Articles and reports
- Product descriptions
- Instructions
- Everyday conversations
- Edited professional writing
Examples:
Please smooth the paper before placing it in the folder.
We want a smooth transition to the new schedule.
The lotion leaves your skin feeling smooth.
If you are reading an older document and encounter smoothe, you do not need to assume that the writer meant a completely different word. The spelling has a documented history as an alternative form.
When One Choice Sounds Wrong
Smoothe can look especially unusual when it appears where readers expect the familiar base form:
Please smoothe the fabric.
For modern US writing, write:
Please smooth the fabric.
The same applies when describing something:
The surface is smooth.
Not:
The surface is smoothe.
Another common mistake is assuming that smoothe is required because the word is functioning as a verb. It is not.
The verb itself is smooth.
The past tense is smoothed, and the -ing form is smoothing.
Common Mistakes (and Quick Fixes)
Mistake 1: Adding an unnecessary e
Wrong for ordinary modern usage:
Smoothe the surface.
Better:
Smooth the surface.
Mistake 2: Treating smooth as only an adjective
Incorrect assumption: The verb needs another spelling.
Correct:
Smooth the wrinkles from the shirt.
The same base spelling works as the verb.
Mistake 3: Confusing smoothe with smoothed
Smoothe is not the normal base verb.
Smoothed is the standard past-tense form:
She smoothed the paper with her hand.
Mistake 4: Assuming a rare spelling creates a new meaning
The presence of smoothe in a dictionary or older text does not establish a separate modern meaning. It is better understood as an alternative spelling related to smooth.
Everyday Examples
Here are natural examples using the standard modern form:
The glass has a perfectly smooth surface.
She smoothed her jacket before the interview.
The road was smooth after the repairs.
We had a smooth checkout process.
Use the back of the spoon to smooth the frosting.
His explanation made the transition sound smooth and simple.
The plane had a smooth landing.
She smoothed out the wrinkles in the document.
Notice that smooth can describe both a physical quality and an experience or process. It can also function directly as a verb without changing to smoothe.

FAQs
Is “smoothe” ever correct?
“Smoothe” does exist as an alternative spelling of the verb in some dictionaries, but it is not the normal modern form. For contemporary US writing, use “smooth” unless you are discussing a historical text or preserving a source’s unusual spelling.
Is “smooth” both an adjective and a verb?
Yes. As an adjective, “smooth” describes an even surface, easy process, or calm movement. As a verb, it means to make something even or to remove difficulties. The spelling stays “smooth” in both roles.
Why does “smoothe” look reasonable?
The extra e can seem natural because English has verbs such as “breathe” and “clothe.” Writers may also notice forms like “smoothes” and assume the base verb is “smoothe.” In fact, “smooth” is already the base verb.
Does “smoothe” have a different meaning?
No modern meaning reliably separates “smoothe” from “smooth” for ordinary US usage. When “smoothe” appears, it generally represents an alternative or historical spelling of the same word rather than a separate modern word with a distinct meaning.
What is the correct past tense of “smooth”?
The correct past tense is “smoothed.” For example, “She smoothed the paper before folding it.” The present participle is “smoothing,” and the third-person singular present form is commonly “smooths.”
Should I write “smooth” in formal writing?
Yes. “Smooth” is the standard choice for school, workplace, edited, and general everyday writing. Using “smoothe” may distract readers because it is uncommon. Choose “smooth” for the clearest contemporary US-English wording.
These choices apply whether you are describing a surface, movement, process, or the act of making something more even.
Conclusion
For modern US English, smooth is the spelling to use.
It works naturally as both an adjective and a verb, and it covers meanings involving even surfaces, steady movement, easy processes, and the act of making something more even or manageable.
Smoothe is not simply an invented form: dictionaries document it as an alternative spelling, particularly for the verb. But its uncommon status makes it unsuitable as the normal choice for contemporary writing.
When in doubt, write smooth:
The surface is smooth.
Smooth the fabric.
She smoothed the paper.
That spelling is clear, familiar, and appropriate for modern American English.
