In any language, in addition to express their primary meanings, words may be used to indicate or suggest some secondary meaning also. This meaning is always different from the primary meaning. In the opinion of Dr. K.Kunjunni Raja. "If we take the word as denoting its normal primary meanings, the sentence may become non-sensical in the context. This produces a 'psychic resistance' in the listener, and there is a sort of break in the flow. It excites attention and requires interpretation for understanding the purport”.
