How someone says something says a lot about them. You’re more likely to entrust your finances to a person who says, “I appreciate your trust in my ability to manage finances” than to a person who says, “Thanks for giving me your money.” They’re basically saying the same thing, right? Another example would be someone that wants to express a cheerful disposition. Doesn’t “wow, this is so much fun” sound more enthusiastic that “this is quite amusing”? Maybe that voice in your head read that second quote in a British accent, but the writing itself does not refer to any specific accent. I’m not saying the British are not amusing; I’m saying that that’s an example of the power of how you use words. The words you use and how you use them say a lot about you, and that is a power in itself.
That last example talked about a British accent. Areas of the world have a vernacular that distinctly refers to certain areas. Using “mate” at the end of a sentence is part of an Australian accent in the same way saying “eh” at the end of a sentence is part of a Canadian accent and “old chap” is part of a British accent (or an accent knocked off from “Great Gatsby”). Even different regions of the same country can have different vernacular. In America, the South is known for a Southern drawl, where they use “y’all.” In my local Bay Area, the west-most coast of California, people are known to use “hella,” which is derived from “hell of a lot of.” In most context, though, “hella” can be replaced by “very” or “a lot of.” However, “hella” is part of local speech. Using “like” unnecessarily is very Californian. Therefore, using and hearing people use “like” and “hella” are common for me here in Bay Area, CA.
How you use words also reflects how you want to present yourself. While I use “hella” and “like” regularly in talking to my friends, I don’t use them when I talk to my boss or my teachers (unless I’m close enough to my teachers). It’s okay to go to a friend and say “It’s, like, hella busy today,” but it’s not okay to say that to your boss. To my boss, if I felt it was even necessary to make small talk, I’d say, “Wow, it’s quite active today.” To a teacher whom I’m not close to, I’d probably say something similar to that but more casual: “Wow, it’s really busy today.”
Your words also reflect your age or even what age you feel most suits you. There are snobby adolescents that try to sound like adults as well as older generations that try to sound youthful. In my experience, those adolescents that try to sound like adults often come off as pretentious, but that may just be my perception. After all, certain words affect people differently.
There is no way to make all people perceive words exactly the same. “This is quite amusing” may not strike everyone as a British remark. There are adults who successfully adopt “hella” and “like” in their speech. People who aren’t Australian may say “mate,” and people who aren’t Canadian may say “eh.” I find myself using “y’all” even though I’m from the west coast of America. Anyone can adopt a form of speech. However, that does not diminish how certain vernaculars make people believe a person using a certain vernacular is a certain way. My advice is to know who you’re talking to and who may hear and where you’re talking.
