MTEL Communication Literacy Skills : Reading Practice Test

The prefix "non-" signifies "not." It is used to negate or indicate the absence of the root word that follows it. For example, "nonexistent" means not existing, and "nonstop" means without stops. This prefix is common in the English language and effectively communicates the concept of negation or lack.

The other choices represent different meanings. "Excessive" implies a surplus or abundance, "all" refers to the entirety of something, and "beside" indicates a position next to or nearby. Each of these terms conveys a distinct concept that is not related to the negation represented by "non-."
