What exactly is the need for building up vocabulary or knowing new words over and above the common words ? I am not asking from academic perspective but trying to grasp the real need for learning new words. Some say that it helps express oneself better but how that’s not possible with the most commonly used words and rare words are anyways perhaps might not be comprehensible as they are uncommon. Isn’t simple and easy better ? Most books use uncommon words that are not spoken in day to day life. Request your views
More words = more specificity.
It’s like painting. You can do it using only primary colors without mixing them at all or just do it black and white. Or you can use all sorts of tones and shades, to achieve your result.
Thank you
