and low tone in ideophones are often connected to largeness and heaviness, whereas voiceless consonants and high tones tend to relate to smallness and lightness. Reduplication figures quite prominently in ideophones, often conveying a sense of repetition or plurality present in the evoked event. The iconicity of ideophones is shown by the fact that people can guess the meanings of ideophones from various languages at a level above chance. However, the form of ideophones does not completely relate to their meaning; as conventionalized words, they contain arbitrary, language-specific phonemes just like other parts of the vocabulary. Grammar The grammatical function of ideophones varies by language. In some languages (e.g. Welayta, Yir-Yiront, Semai, Korean), they form a separate word class, while in others, they occur across a number of different word classes (e.g. Mundang, Ewe, Sotho, Hausa). Despite this diversity, ideophones show a number of robust regularities across languages. One is that they are often marked in the same way as quoted speech and demonstrations. Sometimes ideophones can form a complete utterance on their own, as in English "ta-da!" or Japanese . However, in such cases the word ideophone is used as a synonym to interjection. Proper ideophones may occur within utterances, depicting a scene described by other elements of the utterance, as in Japanese Taro wa sutasuta to haya-aruki o shita "Taro walked hurriedly' (literally 'Taro did haste-walk sutasuta'). Ideophones are more like illustrations of events than responses to events. An ideophone like Gbaya kiláŋ-kiláŋ 'in a zigzagging motion' displays a certain resemblance to the event (for instance, its irregular vowels and tones depicting the irregularity of the motion). Registers Languages may differ in the context in which ideophones are used. In some languages, ideophones are primarily used in spoken language (e.g. narrative contexts) and are rarely encountered in written language. In other languages (e.g. Ewe, Japanese), ideophones can be freely used in all registers. In general, however, ideophones tend to occur more extensively in spoken language because of their expressive or dramaturgic function. Examples Japanese The Japanese language has thousands of ideophones, often called mimetics. The constructions are quite metrical 2-2, or 3-3, where morae play a role in the symmetry. The first consonant of the second word of the reduplication may become voiced if phonological conditions allow. Japanese ideophones are used extensively in daily conversations as well as in the written language. doki doki () – heart-pounding kira
