Incorrect spelling


Incorrect spelling, explanation: the present participle of the verb choose must be spelled choosing because the derivative is based on adding the suffix -ing to the base word. Since the root is choose written with two vowels, one can’t change the spelling by removing one of the -o. That’s why the correct form is choosing and the incorrect one is chosing.

Correct spelling


Correct spelling, explanation: this word is a merge of the verb choose and the ending -ing. Therefore, the right form must be spelled choosing – with the double -o. Chosing is a mistake and it may come from the past tense form of choosechose.
