* Prefix: A prefix is a word part added to the beginning of a word to change its meaning. "Dis-" is a common prefix meaning "not" or "opposite of." However, in "disappeared," "dis-" is not a prefix, but rather a part of the base word itself.
* Suffix: A suffix is a word part added to the end of a word to change its meaning or grammatical function. While "ed" is a common suffix indicating past tense, in "disappeared," "ed" is part of the base word "appear."
Breakdown:
* The base word is "appear," which means "to come into view."
* The prefix "dis-" adds the meaning of "not" or "opposite of" to the base word, making it "disappear."
Therefore, "disappeared" is a single word that is formed by combining the prefix "dis-" with the base word "appear" and then adding the past tense suffix "-ed."
