Is “de” Always a Prefix?

Keep note of the fact that de is always not a prefix. For instance, the word “deal” is not “de-al,”. Similarly, the word “dental” is not “de-ntal.” Deal and dental have no prefixes. The de- in each of them cannot be considered as a prefix but rather an innate part of the terms.

You can know if the de- in the word is a prefix if the root word is understandable by itself and without the prefix. Alternatively, you can substitute de- with another prefix, such as en-, re-, a-, and in-. If the word is meaningful then the de- there is used as a prefix.

For Example, take the word “descend”. To check if de is used as a prefix, replace it with an a- prefix. The word “ascend” is formed. “Ascend” has the opposite meaning of “descend”. Hence de- becomes the prefix of the word.
