It has been stated many times that the principal idea in the repetition of words is that of emphasis or intensity. My observation has led me to conclude that this is incorrect, and that the true sense in almost every case is one of the following:—
distribution (over time, space, or a number of objects), pleasantness, no meaning at all.
In order to make the inquiry practical, it is better to confine it to cases of words repeated without alteration. If anyone will in the course of his reading take 1,000 consecutive instances of repetition, he will find that (i) short words are repeated far oftener than long,(ii) repetition of adjj. or advv. with a pleasant meaning is much commoner than of those with a nasty meaning, and when the meaning may be either good or bad, the good is intended,(iii) nearly every instance comes under either distribution or pleasantness.
