Correct spelling


Correct spelling, explanation: the word subcategories has to be spelled with consideration – because of the accumulation of the vowels that can be very tricky. You should be careful not to make a mistake. This plural noun consists of two parts: the prefix sub- and the root categories (that comes from category). It can’t be written down as subcatagories, because it’s just an error. Subcategories is the only correct form.

Incorrect spelling


Incorrect spelling, explanation: you shouldn’t spell this word as subcatagories, because this word doesn’t exist. The only correct version is subcategories and it’s a combination of two elements: the prefix and the root. The prefix is sub- and it means under, beneath, subsidiary, secondary, almost, nearly. The root on the other hand is the plural noun categories. As you can see, it has two -e vowels, not two -a vowels.
