The word “fidelity” is derived from the Latin roots for “faith” and is found in other words like “confident” and “infidel.” When someone shows fidelity, that person is faithful to someone or something. For instance, to say, “Raul showed fidelity to his wife all throughout their marriage, never once breaking the trust of their marriage vows.”

The word “marine” means “related to the sea.” It is derived from the Latin for “sea” and is found in words like “maritime” and “submarine.” A “mariner” is another word for a sailor—a person who does his work “on the sea.”

The root "ego" is derived from the Latin word forselfand the suffix "-centric" meanscentered on or around, so it makes sense that “egocentric” meansthinking most of oneself, or“narcissistic.”“Magnanimous” meansgenerous, particularly with money; “prodigal” meanswasteful with money; “revolting” meansdisgustingorrebelling, and "lucid" meansclearoreasy to understand.

The prefix "con-" meanswith, and "-curr-" derives from the Latin forrun, so it makes sense that “concurrent” meansrunningtogether, or in other words,happening at the sametime, or “simultaneous.” “Esoteric” meanslikely to be understood by a small number of people, rarefied,orabstract; “antecedent” meansforerunnerorsomething that comes before another thing; “antipathy” ishostilityoranimosity; and “reverence” isdeep respectorworship.

The prefix "re-" can meando again, and the Latin root "juven" meansyouth, so it makes sense that "rejuvenate" meansmake someone or something look or feel young again. This is very close to the meaning of the word “revitalize,” which meansgive new life to. As for the other answer choices, “homogenize” meansmake uniformorstandardize; “grovel” meansbeg while on one's knees on the ground; “truncate” meansshorten; and “pardon” meansofficially forgive.

Do not be tricked into thinking that the word “luster” is related to “lust.” The two words come from very different bases. “Luster” is related to the same Latin root from which we get the word “illustrate.” The root meansto illuminate. (An illustration “illuminates” a topic by making it visible to the eye.) The best meaning for “luster” is therefore “glow.” Something with a luster has a sheen or brightness that glows.

The word deluge comes from the Latin for “to wash away.” The “-luge” portion means “wash” and is found in words like “dilute” and “ablution” (the washing of oneself). Often, one finds the word used in literary sources referring to “the Deluge,” referring to the Biblical story of Noah’s ark and the flood. At times, the word “antediluvian” is used to insult something by implying that something is “older than Noah’s flood.” Note that the word “deluge” can be used to indicate not only a flood of water but also any great amount happening at one time.

The word “current” comes from the Latin for “to run.” Although it can mean “concerning the present moment,” it can likewise mean “to flow,” as when someone talks about the flow of water or electrical current (the “flow of electrons”). This general meaning is the one that is most appropriate among the answer options.

The word “genre” is related to the Latin “genus,” a term that we still use in logic to mean “general kind.” For instance, when someone says “man is a rational animal,” the general class “animal” is the genus into which “man” is placed (so to speak). When we speak of “genres of music,” what we really mean are “classes” or “general types” of music. For instance, one might say, “The most popular genres of music are baroque organ and renaissance polyphony, not rock and ska.”

The word “gusto” is perhaps a bit informal; however, it is regularly used in speech and even somewhat formal writing. Often, you will see it expressed in some form similar to, “Since he greatly loved his work, John performed it with gusto, always ready to take on a new task.” In such contexts, the word means “enthusiasm,” “readiness,” or even “enjoyment.” It is related to the Latin for “taste,” which can be found in “gustatory” as well as “digest.” If someone “has a taste” for something, he or she likely has a great love for it and does it with much enthusiasm.
