Using Prefixes, Suffixes, and Roots to Identify Synonyms - SSAT Elementary Level Verbal

"Dishonest" means not honest or untrustworthy.

"Subterranean" means underground: It contains the prefix ­"sub_-_," which means under or below, and the root "terra," which comes from the Latin word for earth. So, "underground" is the best answer, because it is closest in meaning to "subterranean."

"Extraterrestrial" means alien when used as an adjective, and an "extraterrestrial" is is an alien. So, "alien" is the correct answer. To help you understand the formation of words, consider that "terrestrial" means from the earth and in this context, the prefix "extra-" means something other than. So an extraterrestrial is something from somewhere other than the earth. To help you further, "extraordinary" means something other than ordinary, "ordinary" means normal, a "foreigner" is someone from another country, and a "citizen" is a member of a nation.

The prefix "im-" means not, as in the words "impossible," "impolite," and "improbable." So, "impermanent" means temporary or not permanent, and "temporary" is the correct answer.

"Abnormal" is defined as unusual or not normal. "Atypical" is defined is not typical, so "atypical" is the best answer choice. The prefixes "a-" or "ab-" can mean not, as is demonstrated in "abnormal" and "atypical" respectively meaning not normal and not typical.

To “surpass” is to go beyond or to become better than someone or something. “Exceed” also means to go beyond the limit of something or to become better than someone or something. Look for prefixes like "sur-" and "ex-"where "sur-" can mean above and "ex-" can mean out of. To further help you, “recede” means to go back, so you can say waves “recede” on the shore.

If you are “hypersensitive” you are overly sensitive to things. For example, you may easily have your feelings hurt. The prefix "hyper-" usually means overly.

The prefix "under_-"_ means below or beneath, so the word “underdeveloped” means not grown enough, not developed enough. To provide further help, “developed” means grown; “beneath” means under.

The suffix "-act" means to do, to act, to respond. The word “react” means respond to something. To provide further help, “writhe” means twist in pain; “egress” means exit, way out; “akin” means similar to; “variegated” means different looking, multicolored.

The prefix "infra-" generally means below or under, so the word “infrastructure” means basic structure or "foundation." To provide further help, a “trial” is a test; a “variable” is something that can change; a “luminary” is a famous or successful person.

The prefix "over-" means completely, excessively, too much, so the word “overburdened” means carrying too much of a load, or "overloaded.” To provide further help, “overlook” means ignore; “overhead” means above; "overt" means secret.

The prefix "semi-" usually means half, so we can assume that a “semicircle” is half a circle. To provide further help, a three-dimensional circle is called a “sphere;” “parallel” means running alongside, having the same slope; “slope” means slanted ground; “gradient” means slope. In addition to being terms we use in English, these are also all mathematical terms.

“Dismount” means to get down. It is commonly used when speaking about “dismounting" from horses, as in to get off your mount. The prefix "dis-" is a negation prefix and the suffix "-mount" refers to something you sit on.

The prefix "un-" is a negation prefix and usually means not, so the word “unacceptable” means not acceptable. Of the answer choices, this is closest in meaning to “intolerable,” which means not tolerable. The prefix "in-" is used very much like the prefix "un-." To provide further help, “unmitigated” means not mitigated, pure; “domesticity” is life inside the home; “meticulous” means careful, paying great attention to detail; “incomprehensible” means not able to be understood.

The prefix "under-" means beneath or below, so the word “underage” means below age, immature. To provide further help, a “novice” is a beginner and an “expert” is someone who has been doing something for a long time and is very good at it; a “vendor” is someone who sells things; a “genius” is someone who is very smart.

The prefix "a-" means not, so “atypical” has the opposite meaning of “typical.” Something that is “typical” is predictable, boring, or common, so “atypical” is closest in meaning to “uncommon.” The prefix "un_-" functions here in the same way as the prefix "a-_" does in "atypical"; it negates the meaning of the word. As for the other answer choices, “zealous” means passionate; “derogatory” means disrespectful, rude, or offensive; “wary” means cautious, anxious, or careful; and "traitorous" means treacherous or betraying the trust of someone or a group.

The prefix "ex_-_" means out or away, so to “exhale” means to breathe out, just like to “inhale” means to breathe in. That makes "breathe" the closest synonym to "exhale" amongst the answer choices. As for the other answer choices, "whine" means moan or complain about something.

The prefix "an-" means toward, to join, or to add onto. The word “annex,” when used as a verb, means add or join, and it is most commonly used when talking about adding territory to an existing defined area of land , as in “In the twentieth Century the United States annexed the islands of Hawaii.” The best answer, therefore, is “add.” None of the other answer choices are close in meaning to "annex": “accommodate” is verb that means provide someone with a house or help by making changes to the way in which one regularly does something; "sing" means audibly perform a song; and "sort" means categorize or physically arrange into categories.

You can take a good guess at what "dishonesty" means by noticing the "dis-" prefix that leads the word. "Dis-" is sometimes used as a negative prefix that, when added to a word, makes the new word mean the opposite of what the word added on to typically means, as in words like "disentangle," which means the opposite of "entangle." It's thus not surprising that "dishonesty" means the opposite of "honesty," or on other words, deception, deceit, or intentional trickery. Someone may be dishonest by "cheating" on a test and taking advantage of the "ignorance" of others, they may want to keep this a "secret," and they may feel "guilt" at having been dishonest, but none of these answer choices mean the same thing as "dishonesty," so none can be the correct answer. Only "deception" is close in meaning to "dishonesty," so it is the correct answer.
