The term "et cetera" is an abbreviation of the Latin phrase "et cetera, et cetera," which means "and the rest, and the rest." It is commonly used as a way to indicate that there are other things or details that could be mentioned, but they are not necessary to include in the current context. In other words, "etc" is a way to imply that there are additional items or information, but the speaker/writer does not feel it is necessary to list them all.
