{{Japanese writing}}
{{Nihongo||音読み|'''On'yomi'''|{{IPA|ja|oɰ̃jomi|}}, {{lit}} "sound(-based) reading"}}, or the [[Sino-Japanese vocabulary|Sino-Japanese]] reading, is the reading of a [[kanji]] based on the historical Chinese pronunciation of the character. A single kanji might have multiple ''on'yomi'' pronunciations, reflecting the Chinese pronunciations of different periods or regions.<ref name="Coulmas">{{cite book|last = Coulmas|first = Florian|date = 1991|title = Writing Systems of the World | page = 125| isbn = 978-0631180289}}</ref><ref name="Shibatani">{{cite book|last= Shibatani|first= Masayoshi|title = The Languages of Japan|date = 2008|publisher = Cambridge University Press|pages = 130|isbn = 978-0521369183}}</ref> ''On'yomi'' pronunciations are generally classified into ''[[go-on]]'', ''[[kan-on]]'', ''[[tō-on]]'' and ''kan'yō-on'', roughly based on when they were borrowed from China.
Generally, ''on'yomi'' pronunciations are used for technical, compound words, while the native ''[[kun'yomi]]'' pronunciation is used for singular, simpler words.
== Usage ==
''On'yomi'' primarily occur in {{nihongo|multi-kanji compound words|熟語|jukugo}}, many of which are the result of the adoption, along with the kanji themselves, of Chinese words for concepts that either did not exist in Japanese or could not be articulated as elegantly using native words. This borrowing process is often compared to the [[List of English words with dual French and Anglo-Saxon variations|English borrowings from Latin, Greek, and Norman French]], since Chinese-borrowed terms are often more specialized, or considered to sound more erudite or formal, than their native counterparts (occupying a higher [[linguistic register]]). The major exception to this rule is [[Japanese family name|family name]]s, in which the native ''kun'yomi'' are usually used (though ''on'yomi'' are found in many personal names, especially men's names).
Kanji invented in Japan ([[kokuji]]) would not normally be expected to have ''on'yomi'', but there are exceptions, such as the character {{Nihongo2|働}} "to work", which has the ''kun'yomi'' "''hatara(ku)''" and the ''on'yomi'' "''dō''", and {{Nihongo2|腺}} "gland", which has only the ''on'yomi'' "''sen''"—in both cases these come from the ''on'yomi'' of the phonetic component, respectively {{Nihongo2|動}} "''dō''" and {{Nihongo2|泉}} "''sen''".
== Characteristics ==
In Chinese, most characters are associated with a single Chinese sound, though there are distinct [[literary and colloquial readings of Chinese characters|literary and colloquial readings]]. However, some homographs ({{lang|zh|多音字}}) such as {{lang|zh|行}} (Mandarin: ''{{lang|zh-latn-pinyin|háng}}'' or ''{{lang|zh-latn-pinyin|xíng}}'', Japanese: ''an, gō, gyō'')<!--in go'on. in kan'on, both are ''kō''--> have more than one reading in Chinese representing different meanings, which is reflected in the carryover to Japanese as well. Additionally, many Chinese syllables, especially those with an [[entering tone]], did not fit the largely consonant-vowel (CV) [[phonotactics]] of classical Japanese. Thus most ''on'yomi'' are composed of two [[Mora (linguistics)|morae]] (beats), the second of which is either a lengthening of the vowel in the first mora (to ''ei'', ''ō'', or ''ū''), the vowel ''i''<!--eg. ''ai'', ''sui''-->, or one of the syllables ''ku'', ''ki'', ''tsu'', ''chi'', ''fu'' (historically, later merged into ''ō'' and ''ū''), or moraic ''n'', chosen for their approximation to the final consonants of Middle Chinese. It may be that [[Yōon|palatalized consonants before vowels other than ''i'']] developed in Japanese as a result of Chinese borrowings, as they are virtually unknown in words of native Japanese origin, but are common in Chinese.
== Classification ==
Generally, ''on'yomi'' are classified into four types according to their region and time of origin:<ref name="Coulmas"/>
*{{Nihongo||呉音|'''[[Go-on]]'''|"Wu sound"}} readings derive from the pronunciation used in the [[Northern and Southern dynasties]] of China during the 5th and 6th centuries, primarily from the speech of the capital [[Jiankang]] (today's Nanjing). They are related to [[Wu Chinese]] and the [[Shanghainese language]].
*{{Nihongo||漢音|'''[[Kan-on]]'''|"Han sound"}} readings come from the pronunciation utilized during the [[Tang dynasty]] of China in the 7th to 9th centuries, primarily from the standard speech of the capital, [[Chang'an]] (modern [[Xi'an]]). Here, ''Kan'' refers to [[Han Chinese|Han Chinese people]] or [[China proper]].
*{{Nihongo||唐音|'''[[Tō-on]]'''|"Tang sound"}} readings are based on the pronunciations of later dynasties of China, such as the [[Song dynasty|Song]] and [[Ming dynasty|Ming]]. They cover all readings adopted from the [[Heian era]] to the [[Edo period]]. This is also known as {{Nihongo||唐宋音|Tōsō-on|Tang and Song sound}}.
*{{anchor|kan'yō-on|kan'yōon|kan'you-on}} {{Nihongo||慣用音|'''Kan'yō-on'''|"customary sound"}} readings, which are mistaken or changed readings of the kanji that have become accepted into the Japanese language. In some cases, they are the actual readings that accompanied the character's introduction to Japan but do not match how the character [[linguistic prescription|"should"]] (is prescribed to) be read according to the rules of character construction and pronunciation.
The most common form of readings is the ''kan-on'' one, and use of a non-''kan-on'' reading in a word where the ''kan-on'' reading is well known is a common cause of reading mistakes or difficulty, such as in {{Nihongo||解毒|ge-doku|detoxification, anti-poison}} (''go-on''), where {{Nihongo2|解}} is usually instead read as ''kai''. The ''go-on'' readings are especially common in [[Buddhist]] terminology such as {{Nihongo||極楽|gokuraku|paradise}}, as well as in some of the earliest loans, such as the Sino-Japanese numbers. The ''tō-on'' readings occur in some later words, such as {{Nihongo||椅子|isu|chair}}, {{Nihongo||布団|[[futon]]|mattress}}, and {{Nihongo||行灯|andon|a kind of paper lantern}}. The ''go-on'', ''kan-on'', and ''tō-on'' readings are generally [[cognate]] (with rare exceptions of homographs; see below), having a common origin in [[Old Chinese]], and hence form [[doublet (linguistics)|linguistic doublets]] or triplets, but they can differ significantly from each other and from modern Chinese pronunciation.
