Here at languageandgrammar.com, one of the points that we like to make is that communication goes beyond grammar. Grammar is important, of course, and we’ve written many posts about it (and will continue to do so), but it’s also important to understand how and why we say the things that we do–and how they will be received by the listener.
Many of the things we say might be poor communication for myriad reasons, including being insincere to inarticulate to too informal to too trendy. All of those affect your communication since you, then, appear to be insincere, inarticulate, inappropriate, or overly trendy. That’s not exactly the type of image you want to foster, now, is it?
Some of the things we say might also be too insensitive to others, and here’s just one good example (The Washington Redskins and Political Correctness).
