Are you learning English everyday or every day? Are you satisfied with your English skills already or all ready? Look at the words written in bold, which is which? Admit it or not, most of us who are learning the language tend to be confused about which form to use in our sentences.

Although both word forms really exist but they do have different functions in a sentence. We sometimes misused these words without even noticing it, thinking that it’s correct and continue using it now. This is one of the common errors that occur in our writing.

We do have words that can be written in two forms namely; the ONE-WORD form and the TWO-WORD form but they mean differently. The ONE-WORD form functions as an adverb, an adjective, or a pronoun while the TWO-WORD form is a phrase that is usually used as an adjective, an adverb, and a noun.

Here are 10 common words that can be written in both forms
