Research into the detailed contextual distribution of sociologically important words, what one might call focal or pivotal words, is only just beginn… - John Rupert Firth

Speech is our most valuable instrument, because we can make it fit our common lives. We are not born to follow words. Words follow life. It has always been so from the very beginning. In fact, the human larynx and the shape of the passages above it have evolved in harmony with the lives our earliest ancestors lived, first in the trees, and then on the ground.

The complete meaning of a word is always contextual, and no study of meaning apart from context can be taken seriously.

The study of such words as work, labour, trade, employ, occupy, play, leisure, time, hours, means, self-respect, in all their derivatives and compounds in sociologically significant contexts during the last twenty years would be quite enlightening. So would the study of words particularly associated with the dress, occupations, and ambitions of women, or the language of advertising, especially of quackery, entertainments, food, drink, or of political movements and propaganda.
