1. return to the most simple or important aspect of something
things are getting too complicated, let's get back to basics
Sometimes, things can get too complicated and it can seem like the old way was the best. This is when people talk about 'getting back to basics', or revisiting an earlier way of doing something. A lot of companies trying to promote organic or environmentally-friendly methods use this expression to advertise their products or services, as a way of stating that they are not using modern or advanced means of production, or they are avoiding additives such as chemicals or synthetics. You'll hear this expression used more in professional contexts than social ones.
