SAT Vocab Monday: Tongue Twister Words


Get your tongues ready for these multisyllabic monstrosities. If you watch the video, even I—the SAT dude—stumble over a couple of pronunciations. Luckily, the SAT won’t ask you to pronounce any words. But you’ll be better off if you know the definitions of these words.


Not only is this word a mouthful, it’s also confusing. Given that fatigue is tiredness and adding de- to the front of the word negates and adding in- to the front of the word, typically (but not always!) negates it, it looks like we are dealing with a double and that the meaning of the word is tired. However, one who is indefatigable never tires; they keep at it. Martin Luther King was an indefatigable opponent of unequal treatment of African Americans.


This word means very similar to real life. Animation that has a high degree of verisimilitude looks very similar to real life. I’ve seen certain video games that look as though they are a movie, with real-life actors. A good way of thinking about verisimilitude is a mixture of realism and plausibility. As far as true to life goes video games have almost zero verisimilitude. If you are driving down the video game road in your video game Ferrari and you drive into an oncoming video game truck, all you have to do is push the restart button.


Another confusing word, this beast of a word to pronounce (see video) has nothing to do with the infinite (think space spreading out forever). Instead, it has to do with the very small. The time difference between a runner who wins the 100-meter dash in 9.91 seconds and the runner-up (as it were) who finishes in 9.92 is infinitesimal. The difference between the medals’ respective prestige, however, is hardly infinitesimal.


Do you want to take over the world? Do you thirst for complete power, the way Julius Caesar and Napoleon once did? If you answered yes, then you are likely megalomaniacal. The word also implies that the person is often deluded, thinking they have far more power than they actually have. So if you set off into the sunset on one horse and think you are going to conquer a great empire, you are definitely megalomaniacal.
