Synonyms: Roots from Latin

The root "ben" means good, so it makes sense that "benign" means not harmful, not dangerous, or "harmless." As for the other answer choices, “harmful” means causing damage; “helpless” means unable to help oneself; “helpful” means kind and providing assistance; and “horrific” means shocking and terrible.

The Latin root -cess- means go, yield, obtain. So "accessible" means able to be reached, able to be accessed, reachable. Another example of a -cess- word is "exceed" which means to go beyond. Additionally, "fortunate" means lucky; "hapless" means unfortunate, unlucky; "malleable" means flexible, changeable.

The words "alien" and "alienate" come from Latin roots meaning other. Whenever something is "alien," it is foreign to us—it is something "other" in the sense of being different. The verb form "alienate" describes the process of making something appear to be foreign or other. Thus, the only option that is adequate for this question is "isolate." Whenever we "alienate" people, we isolate them from each other.

The word "deride" comes from the Latin word for to laugh. Whenever we "ridicule" someone, we mock that person or "laugh at them." In a way, you can think of the expression "being a laughing stock." This means that someone is being ridiculed or derided. When we "deride" someone, we mock that person. Mockery is a mean way of "making fun of" someone. (Do you see that the word "deride" has a form similar to "ridicule"? Both words come from the Latin "ridere," meaning to laugh.)

The word "patriarch" comes from the Latin word "pater," which means father. A "patriarchy" is a kind of society in which fathers (and males in general) have the most power. This is contrasted to a "matriarchy" in which mothers (and women in general) have power. ("Mater" is the Latin word for mother.) Now, "patriarch" could be any male ancestor. Thus, Jewish people refer to Abraham as being one of their patriarchs, for they see him as being a "father" to their people. It is also fine to refer to any father as a "patriarch." Indeed, even the word "father" can often be used to describe an important ancestor or figure who is not an immediate father. In this respect, think of the expression, "Founding fathers" often used to describe those men who played a key role in the founding of the American republic.

The word "solitary" comes from the Latin root for alone—"solus." When someone has a "solo" in a concert, he or she plays or sings a part all by himself or herself. This should not be confused with "solar," which has to do with the sun. Now, when someone is isolated, he or she is also alone. The word "isolated" comes from the Latin for island, which is also found in words like "insular" and "insulation." Thus, the best option provided among those given here is the word "isolated." This is a primary meaning when we have expressions like "solitary confinement," meaning, "isolated imprisonment."

The prefix "tact-" means related to touch, so “tactile” means able to be touched. To provide further help, “audible” means able to be heard; “visible” means able to be seen. Notice that the suffix "-ible" means able to be.

The word "stellar" comes from the Latin word "stella," meaning star. Thus, something that is called "stellar" is something that is as bright and rare as a star. This is meant to describe something that is marvelous, outstanding, or superlative. The word can also describe things in outer space—like stars. Thus, one would speak of "stellar phenomena," but none of the options pertain to that meaning. Do not be tempted by options like "scientific" and "telescopic."

The Latin root "mal-" means bad and appears in English words like "malcontent" (someone who instigates trouble due to not being content with the current state of things); "malady" (sickness), and "maladroit" (not adroit, therefore clumsy and uncoordinated). Because of this, it makes sense that "malice" means ill-will or spite, making "malevolence" the correct answer, as "malevolence" means vindictive, evil, or hostile. The opposite of “malevolence” is “benevolence,” which means wishing or doing good things for others. (The prefix "ben-" means good.) “Magnificence” means greatness; “magnanimity” means nobility, kindness and generosity; “benefit” means something or some aspect of something that is useful, good, and helpful.

The Latin root -cogn- means know, knowledge, as in "recognize" which means to notice or know someone. So, "incognito" means in disguise, dressed up so no one will know you. Additionally, "revealed" means displayed, shown after previously being hidden; "despised" means hated; "surmised" means guessed at, estimated at, determined is true without conclusive evidence; "redundant" means no longer useful because it has been replaced by something better.
