Correct spelling


Correct spelling, explanation: the correct form of this noun is skier because it is made of the word ski and suffix for describing a person – -er. There is no need to double the vowel when we add another one in a suffix, therefore skiier is incorrect. The only correct form is skier.

Definition of skier:
noun, a person who skis
-Do you ski? -No, I love sports, but I’m not a skier.
My dad is an excellent skier, but we never followed his steps.

Incorrect spelling


Incorrect spelling, explanation: double i form – skiier is a mistake. The word is a combination of ski and suffix -er (skier), which we add to nouns to create a form describing a person. Therefore the correct form is skier.
