Go-on
Go-on or goon (呉音; English: /ˈɡoʊ.ɒn/ GOH-on; Japanese pronunciation: [ɡo.oɴ] or [ɡoꜜoɴ], lit. "Wu sound") are an early layer of Japanese kanji readings (on'yomi), predating kan-on (漢音). Go-on was transmitted with Chinese classical and Buddhist texts and remains particularly common in Buddhist vocabulary.[1] Both go-on and kan-on reflect Middle Chinese pronunciations, adapted to Japanese phonology.[1]
History and uses
[edit]Go-on is the earliest of the three main historical layers of Chinese-based kanji readings, followed by kan-on and tōsō-on.[2]
A common account traces the transmission of go-on to people from Baekje who had contact with the Wu region of southern China during the Six Dynasties.[3] Edwin G. Pulleyblank identifies the Wu of go-on with the old southern capital of Jiankang (modern Nanjing) and its surroundings, where he suggests an older Chinese pronunciation standard was particularly persistent.[4] The Nihon Kokugo Daijiten also records a theory tracing its origins further back, through the Korean Peninsula, to Chinese pronunciations of the Han and Wei periods.[5]

Kan-on was introduced through missions to Tang China and other contacts during the Nara and early Heian periods. Go-on readings continued in use alongside it: 行 is read gyō in shugyō (修行; "Buddhist practice"), but kō in kyūkō (急行; "express train").[1]
Compounds can also mix the two layers. In modern Japanese, for example, gengo (言語; "language") combines kan-on gen with go-on go.[6]: 373 In a study of two historical dictionaries, Hideyuki Ohshima compared selected two-character Sino-Japanese word forms whose characters had distinct go-on and kan-on readings. Mixed readings accounted for about 15% of the forms in the 12th-century Iroha Jiruishō and about 24% in the Nippo Jisho, published in 1603–1604.[6]: 376–380, 388
Some historical go-on readings were lost after kan-on was introduced. Sino-Japanese character dictionaries (kanwa jiten) nevertheless supply go-on readings for their entries, including artificial readings inferred from Chinese fanqie spellings. Marc Hideo Miyake also describes a dictionary that supplied some unattested go-on and kan-on readings by analogy with homophonous characters in the historical Chinese works Guangyun and Yunjing.[7]
Names
[edit]These readings were formerly called wa-on (和音; lit. "Japanese sound"). The name go-on is attested for this reading layer from the mid-Heian period, including in Fujiwara no Kintō's Hokuzanshō (北山抄, compiled c. 1012–1021).[5][8] The Nihon Kokugo Daijiten suggests that this usage imitated a Chinese practice of contrasting southern go-on with kan-on, regarded as the correct pronunciation. It attributes the later theory of a southern Chinese origin to the association of the name with Wu.[5]
Characteristics
[edit]Go-on distinguishes voiced and voiceless consonants that are merged in kan-on. It also has initial m- and n- where kan-on has b- and d-, respectively: 馬 ("horse") has go-on ma and kan-on ba, while 男 ("man") has nan and dan.[9]
| Kanji | Meaning | Go-on | Kan-on | Middle Chinese transcription[10] |
|---|---|---|---|---|
| 明[11] | "bright" | myō | mei | mjaeng |
| 京[12] | "capital" | kyō | kei | kjaeng |
| 上[13] | "up" | jō | shō | dzyangX, dzyangH |
| 下[14] | "below" | ge | ka | haeX, haeH |
In the Middle Chinese transcriptions, X marks the rising tone and H the departing tone.[15]
