A prefix refers to the group of letters that can be added in the beginning of a root word that may or may not change the meaning of the new word. Some of the examples of prefixes are un & dis <span>that means not, </span>mis <span>that means wrong or wrongly, </span>sub that means under,pre <span>that means before in time and a lot more. Some examples of root words with prefixes are the following, </span>undisclosed, dishonest, misspell, subway, prenuptial and others.
The prefix in the word "disclose" is the morpheme "dis".
From the linguistic point of view, affixes (prefix and suffix) are morphemes attached to the root in order to change or add meaning. Prefixes are fronted whereas suffixes are attached to the end of the root. Affixes always encode meaning, in this case the prefix "dis" means "not". Other examples of prefix "dis" could be "disqualify, dislike, disagree, disappear", etc.
For example Mrs. Bennett claims Mr.bennet has no regard for her Nerves when in reality he claims that he is well aware of her Nerves meaning that he agrees she is crazy
