Famous quotes containing the words derived and/or meanings:
“Jesus wept; Voltaire smiled. From that divine tear and from that human smile is derived the grace of present civilization.”
—Victor Hugo (18021885)
“An amoeba is a formless thing which takes many shapes. It moves by thrusting out an arm, and flowing into the arm. It multiplies by pulling itself in two, without permanently diminishing the original. So with words. A meaning may develop on the periphery of the body of meanings associated with a word, and shortly this tentacle-meaning has grown to such proportions that it dwarfs all other meanings.”
—Charlton Laird (b. 1901)
