Synonyms: Suffixes from Latin - ISEE Middle Level: Verbal Reasoning

“Laughable” is an adjective that means “so ridiculous as to be amusing,” so we need to pick out an answer choice that means something like “ludicrous.” That means that “sensible” cannot be the correct answer, because “sensible” means “having good sense,” making it an antonym, not a synonym, of “laughable.” “Ridiculous,” however, is an adjective that means “absurd,” and because “ridiculous” is the answer choice closest in meaning to “laughable,” “ridiculous” is the correct answer.

The suffix "-cide" means related to killing and the prefix "pest-" means related to pests, such as insects or rats. In this instance, since there is no option for “rat killer” the correct answer is “insect killer.”

The prefix "se-" means apart or away, so “segregate” means keep apart.

The prefix equi- means same or equal. A situation that is “equitable” is one that is the same for everyone, equal and fair. To provide further help, “fragile” means easily broken; “ceremonial” means done for reasons of tradition or ceremony.

The Latin root "clar_"_ means clear, so “clarify” means to make clear. “Obscure” means hide when used as a verb; “puzzle” means confuse; "contort" means twist out of shape; and "defy" means purposely disobey a figure of authority.

The Latin suffix -pel means force, as in "repel" which means to force backwards. So, "compel" means force someone to do something, pressure someone. Additionally, "fret" means worry; "proceed" means continue; to "judge" means to make a decision on something based on evidence.

The answer choice closest in meaning to "formulate" is "create." For example, if you "formulate" a plan, it means that you create a plan.

To “maximize” something means t_o make it as high quality or as big as it can possibly be_ or to get as much out of something as possible. That means that "expand" is the best answer choice, as "expand" means make larger. As for the other answer choices, "challenge" means urge to participate in a competitive activity with the speaker or contest or dispute; "undergo" means experience something bad or difficult; "perceive" means notice; and "enliven" means add energy to something, often specifically a social gathering.

The prefix "de-" in "deflect" means away from, and the "-flect" portion of the word means to bend, as it comes from the same roots as the word "flexible" (bendable). So, it makes sense that "deflect" can mean bend away from moving in a straight line, often because of having hit something. To “deflect” can also mean cause something to change direction, or to “sidetrack.”

The "port-" in "portable" derives from the Latin for carry or transport, and the suffix "-able" means able to be, so it makes sense that "portable" means able to be carried easily from place to place. This is close to the meaning of the word “mobile,” which means able to move or be moved easily from one area to another. “Immense” means very big or very important; “laden” means weighed down with or burdened by; "portentous" means ominous or foreboding; and "important" means deserving considerable attention relative to other points or ideas.

The prefix "con-" means together, so it makes sense that to “confer” something means to bring, "award," or present that thing to someone in particular. “Surmise” means guess or suppose something to be true; “foster” means encourage or assist; “undermine” means reduce the importance of, subvert, erode, or weaken; and “fuse” means weld together, join, or combine.

The word "satisfy" comes from Latin roots that mean to make to be enough. The word "satis" in Latin means enough. The suffix "-fy" indicates to do or to make. (This too is from Latin roots, though they are more complex.) Thus, something is satisfying when it is fulfilling. We can sometimes say that food is "satisfying" or "satisfactory," but we might also say that an answer is satisfying or a concert performance is satisfactory. Thus, the correct answer is "fulfill." Something that satisfies fulfills the requirements for that things.

The Latin root -struct- means build. So, to "construct" means to build. Another example of a -struct- word is "destruct," which means to destroy something that has been built. Additionally, "plead" means beg, urge.

The Latin suffix -serv means to keep, to save. So, "preserve" means to save something for the future, to maintain something. To provide additional help, "donate" means give to, usually give to charity; "lend" means allow to borrow; "supplant" means replace.

The Latin suffix -scend means climb, up, go. So, to "ascend" means to climb upwards. Another example of a -scend word is "descend" which means to go down. Additionally, "leap" means to jump high or far.

The Latin suffix -put means think, as in "compute," which means calculate, think about and figure out. So, "dispute" means to disagree, to not agree with what someone thinks. Additionally, "disavow" means renounce, deny; "displace" means either to cause to be moved from it's original position or to replace; "dismember" means take apart, particularly with regard to taking apart a living being. The prefix dis- has many different meanings, but it is generally a "negating" prefix. "Negating" means causing something to mean the opposite.

The Latin suffix -tort means twist, bend, as in "contort," which means to twist one's body. So, "distort" means to twist out of shape, to change something so that it looks unnatural. The closest answer to this is "alter," which means change. Additionally, "confess" means admit to having done something wrong; "increase" means make larger and "decrease" means make smaller; "abandon" means leave behind.

We tend to think of efficient people as being quick at what they do. This is often the case, but the word "efficient" is above all about being able to get things done. It comes from the same Latin root from which we get the suffix "-fy" / "-fication" and several other related forms. All of these mean to do or make. Thus, it is best to use the word "efficient" to refer to someone who is "productive." If a project is just very slow-going, an efficient person may therefore move slowly through the work. However, so long as he or she does it in a productive manner, he or she deserves to be called "efficient."

Notice the little ending on the word "personify." The "-fy" suffix is part of a large family of suffixes and "infixes" (little parts that come inside of words) such as "-fication," "-fac-," and so forth. In general, "-fy" means to do or to make. To "personify" something is to make it a person. Okay, that is a bit strange. But what it means is that one thing makes another thing present in some way. It represents that other thing. Thus, if we say, "Peter personified the very essence of greed," this means that Peter made present the very essence of greed in his person. Thus, "symbolize" is an excellent option.
