go, proceed, advance

Quick Summary

The Latin root vas and its variant vad mean “go.” These roots are the word origins of a fair number of regularly used English vocabulary words, including pervasive and pervade. The roots vas and vad are easily recalled through the words invasive, or a “going” in, and invade, or to “go” into another country to attack it.

The Pervasive Root That's "Gone" to Invade English

The root vas and its variant vad mean “go.” No longer will English vocabulary words containing these roots evade your knowledge of them!

Imagine an enemy force of thousands of pink goblins invading or “going” aggressively into your town. At first they might seem unthreatening, but after they reveal their razor-sharp teeth you would quickly realize that it would be prudent to evade or “go” away from them, lest they eye you for a tasty snack. You might soon realize, to your dismay, that there are so many of these gibbering goblin invaders who have “gone” into your town that you cannot avoid them at all, for they are pervading the lovely place where you live—that is, they’ve “gone” through it to such an extent that you cannot avoid them at all, for they’re pervasive.

Now imagine that you’ve survived the pink goblin invaders—all they wanted was your town’s supply of pink cotton candy. You are now suffering from an invasion of aliens who are “going” into your town to attack it. These three-legged, nine-eyed creatures are invasive because they come in all sizes, “going” into your bathroom towels, your largest buildings, and even your hair. They are so invasive, in fact, that you currently have come up with no evasive techniques enabling you to “go” away from them at all—they’re simply everywhere! Then a clever member of your town suggests giving these pesky invaders some fidget-spinners, and they all become so enthralled with these toys that they forget to eat, eventually starving to death. A perfect evasion tactic that allows you to “go” away from them!

And a vade mecum? That’s a “go” with me, or a handbook that people used to carry about that they couldn’t go without, a latter day version of today’s ubiquitous, information-rich smart phone.

Oh, and Darth Vader? Nope, sorry. Although Annakin Skywalker did “go” to the dark side (and “Darth” does mean “dark”), nevertheless the word “vader” is derived from a Dutch word meaning “father” (hence, Dark Father).
