“A man with a scant vocabulary will almost certainly be a weak thinker. The richer and more copious one’s vocabulary and the greater one’s awareness of fine distinctions and subtle nuances of meaning, the more fertile and precise is likely to be one’s thinking. Knowledge of things and knowledge of the words for them grow together. If you do not know the words, you can hardly know the thing.”- Henry Hazlitt, Thinking as a Science
The importance of Vocabulary has immensely increased over time, with a greater emphasis being laid on communication skills everywhere.
