The word can work as an adjective, verb, noun, and, in some uses, an adverb. Smoothe is not normally used in standard modern English.Smooth or Smoothe.
The confusion often happens because English has many verbs that end in -e, such as “make,” “move,” and “close.”
A learner may think that “smooth” should also become “smoothe” when it is used as a verb. However, English does not always follow that pattern.Smooth or Smoothe.

Can “Smooth” Be Used as Both a Noun and a Verb?

The verb can also be used in expressions such as smooth out. For example, “We need to smooth out the wrinkles” means to remove the wrinkles, while “We need to smooth out a few problems” means to deal with or reduce difficulties.

Common Mistakes Students Make

English learners often try to apply one spelling rule to every word. That is understandable, but English has many words with their own spelling patterns.
“Smooth” looks as if it might need an extra “e” because some English words use “-e” endings. But smooth is already the correct complete form.

Mistake 1: Writing “Smoothe”

Please smooth the paper.
Correction tip: Remember that “smooth” is already complete.
Mistake 2: Writing “Smootheed”
Wrong:
She smootheed her hair.
Correct:
She smoothed her hair.
The past tense is formed by adding -ed to “smooth.”
Mistake 3: Writing “Smootheing”
Wrong:
He is smootheing the wall.
Correct:
He is smoothing the wall.
The final “e” does not belong there.
Mistake 4: Using “smooth” Instead of “smoothly”
Wrong:
The machine is working smooth.
Correct:
The machine is working smoothly.
When the word describes an action, the adverb smoothly is often needed.
Mistake 5: Thinking “Smoothe” Is a More Formal Version
Some learners believe “smoothe” might be a formal version of “smooth.”
It is not.
Smooth is the normal standard spelling, whether your writing is casual or formal.
Easy Trick to Remember the Difference
Here is a simple memory trick:
“Smooth is already smooth—do not add an extra e.”
