In their
Dictionary of Basic Japanese Grammar, Seiichi Makino and Michio Tsutsui point out several other types of sound symbolism in Japanese, that relate
phonemes and psychological states. For example, the
nasal sound gives a more personal and speaker-oriented impression than the
velars and ; this contrast can be easily noticed in pairs of
synonyms such as and which both mean 'because', but with the first being perceived as more subjective. This relationship can be correlated with phenomimes containing nasal and velar sounds: while phenomimes containing nasals give the feeling of tactuality and warmth, those containing velars tend to represent hardness, sharpness, and suddenness. Similarly,
i-type adjectives that contain the fricative in the group
shi tend to represent human emotive states, such as in the words , , , and . This too is correlated with those phenomimes and psychomimes containing the same fricative sound, for example and . The use of the
gemination can create a more emphatic or emotive version of a word, as in the following pairs of words: , , , and many others. ==See also==
