Smoothe Vs Smooth: What Is the Difference & Which Is Correct?

“Smoothe” and “smooth” look nearly identical, but only one is normally accepted in modern standard English. The confusion often comes from adding an extra letter to words that sound as though they might need it. Understanding the difference helps you avoid spelling mistakes and choose the right word confidently in everyday, academic, and professional writing.

Comparison Overview

Smooth is the correct and standard spelling in modern English. It can function as an adjective, verb, noun, or adverb, depending on the sentence.

Smoothe, with an extra e at the end, is generally considered an incorrect spelling when you intend the ordinary English word smooth. It may occasionally appear in historical texts, names, or specialized contexts, but it is not the standard spelling that English learners should use.

For example:

• The table has a smooth surface.
• Please smooth the paper.
• She spoke smoothly during the presentation.

The safest rule is simple: Use “smooth,” not “smoothe,” in standard English.

Standard modern spelling	No	Yes
Common English word	No	Yes
Adjective	Generally incorrect	Yes
Verb	Generally incorrect	Yes
Noun	No in ordinary usage	Yes
Adverb	No	Yes, in certain expressions

Definition of Smoothe

Smoothe is generally an incorrect spelling of the standard English word smooth.

English learners sometimes write smoothe because they expect the word to follow spelling patterns found in words ending in -e. However, the standard spelling does not contain the final e.

For example:

Please smoothe the paper.

This spelling should normally be corrected to:

Please smooth the paper.

Why Does “Smoothe” Look Correct?

The spelling smoothe may look reasonable because English contains many words with silent final e, such as:

• make
• take
• move
• create
• write

However, smooth does not require a final e. Adding one changes the word into a nonstandard spelling in ordinary modern English.

Is “Smoothe” Ever Used?

You may occasionally encounter smoothe in historical material, surnames, place names, brand names, or other specialized contexts. Such appearances do not make it the standard spelling of the everyday adjective or verb.

If you are writing a school assignment, email, article, report, or general piece of English prose, use smooth.

Definition of Smooth

For example:

It can also describe something that happens easily or without problems:
