Analogies: Prefixes from Latin

The prefix "per_-_" comes from the Latin meaning thorough. We see this in words like "perfect" and "pervade." When something permeates something else (e.g. a smell in a room), it completely fills it. Thus, permeate is a kind of "complete filling." To be "satiated" is to be satisfied completely. This is a kind of "complete satisfaction."

When someone is "vexed," he or she is annoyed. This is the opposite of being calm. Therefore, we are looking for a word that is an antonym for "after." he prefix "ante-" comes from Latin and means before. It is found in words like "antechamber" and "antecede." Something that is "anterior" is before something else. This is the opposite of being "after."

To "vanquish" someone is to completely defeat him or her. Therefore, we are looking for a word that intensifies the meaning of "finish," giving the sense of being wholly finished. The prefix "per-" is from a Latin root meaning throughout, though it often means "thoroughly" or "completely." When something is perfected, it is completely made—it is totally finished.

The prefix "juxta_-_" comes from the Latin meaning close. When two things are juxtaposed, they are bordering on each other (like neighboring plots of land). Just as juxtaposition is a close placement with regard to location, so is being "instantaneous" a kind of being close with regard to time.

Someone who is malicious is not benevolent. Being benevolent means being "good-willed"—quite the opposite of someone with a malicious will, a bad will! Therefore, we are looking for something that is the opposite of "extraneous." The prefix "extra-" means outside of. Extraneous details are unimportant and irrelevant—as when someone tells you all about the recent weather when you ask him or her to give you an outline of the a class you missed. Therefore, extraneous details are not relevant.
