As copyeditor here at Gear Patrol, I’m responsible for the words. All the words. All the thousands of words that you read every day (if you’re loyal) on this esteemed publication. So by the nature of my job, it’s in my best interest to know enough words to fill an SAT coursebook. (To this day I’m convinced that “obfuscate” is the word that got me a 710 in critical reading.)
There are plenty who pay their bills with words — journalists, marketers, social media workers (someday there’ll be a tidy word for that) — and there are more than plenty who don’t. But monetary necessity needn’t be the sole prerequisite for a robust vocabulary. For instance, with Americans consuming more news via digital media, it’s good to identify when we’re being misled or manipulated with words (like how that last sentence could easily be replaced with “A wordy job isn’t the only reason you should know a lot of words”).
On a less cynical note, we all use email and text messaging, so strengthening vocabulary is just another way of empowering ourselves to communicate more efficiently and with clearer intention, and to better hear others. It also allows us to better understand ourselves, to hear and understand the words we use out of habit, and what they in turn say about us.
When you reach that point in life where you have no verbal tests to study for, you can easily find your language restricted to the routine setting of your life, limited from a lack of exposure to anything other than the day-to-day necessities. Breaking out of that takes effort, but there are ways. Here are a few.

1Get a dictionary app. Every English teacher I ever had told me I should keep a dictionary in my backpack at all times, never mind the fact that the sheer girth of a such a thing protruding from a bag is enough to give a kid scoliosis. Luckily, dictionaries are now available on every smart device you’re likely to own. Having the free Merriam Webster app on my phone has made it easy not only to check definitions on the go, but to quickly look up whether I was using a word correctly, in writing and in conversations with my girlfriend on the subway (to her chagrin).
Likewise, when you’re reading, don’t be lazy — look up words you don’t know. Flipping over to your dictionary app in mid-sentence won’t throw you off as much as you think; it’ll enhance your understanding of a sentence that uses a word you’re not 100 percent sure about, and your confidence in your grasp of whatever it is you’re reading. Similarly, your Kindle has a built-in dictionary that makes looking up words more intuitive than ever; you have no excuse not to use it.
