Cantonese syllables

A syllable generally corresponds to a word or character. Most syllables are etymologically associated with either standard Chinese characters or colloquial Cantonese characters. Modern linguists have discovered there are about 1,760 syllables being used in the entire Cantonese vocabulary, which cover the pronunciations of more than 10,000 Chinese characters. Therefore, the average number of homophonous characters per syllable is six.
Phonetically speaking, a Cantonese syllable has only two parts – the sound and the tone.

Sounds

A Cantonese sound (or sound segment) usually consists of an initial (onset

Onset may refer to:*Onset , the beginning of a musical note or sound*Interonset interval, a term in music*Syllable onset, a term in phonetics and phonology*Onset, Massachusetts, village in the United States...

). There are about 630 sounds in the Cantonese syllabary.

Some of these, such as /ɛː˨/ and /ei˨/ (欸), /pʊŋ˨/ (埲), /kʷɪŋ˥/ (扃) are not common any more; some such as /kʷɪk˥/ and /kʷʰɪk˥/ (隙), or /kʷaːŋ˧˥/ and /kɐŋ˧˥/ (梗) which has traditionally had two equally correct pronunciations are beginning to be pronounced with only one particular way uniformly by its speakers (and this usually happens because the unused pronunciation is almost unique to that word alone) thus making the unused sounds effectively disappear from the language; while some such as /kʷʰɔːk˧/ (擴), /pʰuːi˥/ (胚), /jɵy˥/ (錐), /kɛː˥/ (痂) have alternative nonstandard pronunciations which have become mainstream (as /kʷʰɔːŋ˧/, /puːi˥/, /tʃɵy˥/ and /kʰɛː˥/ respectively), again making some of the sounds disappear from the everyday use of the language; and yet others such as /faːk˧/ (謋), /fɐŋ˩/ (揈), /tɐp˥/ (耷) have become popularly (but erroneously) believed to be made-up/borrowed words to represent sounds in modern vernacular Cantonese when they have in fact been retaining those sounds before these vernacular usages became popular.

On the other hand, there are new words circulating in Hong Kong which use combinations of sounds which had not appeared in Cantonese before, such as get1 (note: this is non standard usage as /ɛːt/ was never an accepted/valid final for sounds in Cantonese, though the final sound /ɛːt/ has appeared in vernacular Cantonese before this, /pʰɛːt˨/ - notably in describing the measure word

, the first and fourth tones are the "flat tones" (平聲), while the rest are the "oblique tones" (仄聲). This follows their regular evolution from the four tones of Middle Chinese.

The first tone can be either high level or high falling usually without affecting the meaning of the words being spoken. Most speakers are in general not consciously aware of when they use and when to use high level and high falling. In Hong Kong, most speakers have merged the high level and high falling tones. In Guangzhou, the high falling tone is disappearing as well, but is still prevalent among certain words, e.g. in traditional Yale Romanization with diacritics, sàam (high falling) means the number three 三, whereas sāam (high level) means shirt 衫.

The numbers "394052786" when pronounced in Cantonese, will give the nine tones in order (Romanisation (Yale

The distinction of voiced and voiceless consonants found in Middle Chinese was preserved by the distinction of tones in Cantonese. The difference in vowel length further caused the splitting of the dark entering tone, making Cantonese (as well as other Yue Chinese branches) one of the few Chinese languages to have further split a tone after the voicing-related splitting of the Middle Chinese four tones.

Cantonese is special in the way that the vowel length can affect both the rime and the tone. Some linguists believe that the vowel length feature may have roots in the Old Chinese

-like meaning "that familiar example" to a standard word. For example, the word for "woman" in a modified tone means "daughter". They are comparable to the diminutive suffixes 儿 and 子 of Mandarin. In addition, modified tones are used in compounds, reduplications and direct address to family members. The two modified tones are high level, like tone 1, and mid rising, like tone 2, though for some people not as high as tone 2. The high level changed tone is more common for speakers with a high falling tone; for others, mid rising (or its variant realization) is the main changed tone, in which case it only operates on those syllables with a non-high level and non-mid rising tone (i.e. only tones 3, 4, 5 and 6 in Yale and Jyutping romanizations may have changed tones). However, in certain specific vocatives, the changed tone does indeed result in a high level tone (tone 1), including speakers without a phonemically distinct high falling tone.

Historical change

Like other languages, Cantonese is constantly undergoing sound change
Sound change
Sound change includes any processes of language change that affect pronunciation or sound system structures...

, processes where more and more native speakers of a language change the pronunciations of certain sounds.

One shift that affected Cantonese in the past was the loss of distinction between the alveolar and the alveolo-palatal (sometimes termed as postalveolar) sibilants, which occurred during the late 19th and early 20th centuries. This distinction was documented in many Cantonese dictionaries and pronunciation guides published prior to the 1950s but is no longer distinguished in any modern Cantonese dictionary.

Publications that documented this distinction include:
  • Williams, S., A Tonic Dictionary of the Chinese Language in the Canton Dialect, 1856.
  • Cowles, R., A Pocket Dictionary of Cantonese, 1914.
  • Meyer, B. and Wempe, T., The Student's Cantonese-English Dictionary, 3rd edition, 1947.
  • Chao, Y. Cantonese Primer, 1947.


The depalatalization of sibilants caused many words that were once distinct to sound the same. For comparison, this distinction is still made in modern Standard Mandarin, with most alveolo-palatal sibilants in Cantonese corresponding to the retroflex
Retroflex consonant
A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology...

 sibilants in Mandarin. For instance:
Sibilant Category Character Modern Cantonese Pre-1950's Cantonese Standard Mandarin
Unaspirated affricate /tsœːŋ/ (alveolar) /tsœːŋ/ (alveolar) /tɕiɑŋ/ (alveolo-palatal)
/tɕœːŋ/ (alveolo-palatal) /tʂɑŋ/ (retroflex)
Aspirated affricate /tsʰœːŋ/ (alveolar) /tsʰœːŋ/ (alveolar) /tɕʰiɑŋ/ (alveolo-palatal)
/tɕʰœːŋ/ (alveolo-palatal) /tʂʰɑŋ/ (retroflex)
Fricative /sœːŋ/ (alveolar) /sœːŋ/ (alveolar) /ɕiɑŋ/ (alveolo-palatal)
/ɕœːŋ/ (alveolo-palatal) /ʂɑŋ/ (retroflex)


Even though the aforementioned references observed the distinction, most of them also noted that the depalatalization phenomenon was already occurring at the time. Williams (1856) writes:
Cowles (1914) adds:
A vestige of this palatalization difference is sometimes reflected in the romanization scheme used to romanize Cantonese names in Hong Kong
Hong Kong Government Cantonese Romanisation
The Hong Kong Government Cantonese Romanisation is the more or less consistent way for romanising Cantonese proper nouns employed by the Hong Kong Government departments and many non-governmental organisations in Hong Kong...

. For instance, many names will be spelled with sh even though the "sh sound" (/ɕ/) is no longer used to pronounce the word. Examples include the surname 石 (/sɛːk˨/), which is often romanized as Shek, and the names of places like Sha Tin
Sha Tin
Sha Tin, also spelled Shatin, is an area around the Shing Mun River in the New Territories of Hong Kong. Administratively, it is part of the Sha Tin District.-Geography:...

 (沙田; /saː˥ tʰiːn˩/).

After the shift was complete, even though the alveolo-palatal sibilants were no longer distinguished, they still continue to occur in complementary distribution

Canton romanization attempts to reflect this phenomenon in its romanization scheme, even though most current Cantonese romanization schemes don't.

The alveolo-palatal sibilants occur in complementary distribution with the retroflex sibilants in Mandarin as well, with the alveolo-palatal sibilants only occurring before /i/, or /y/. However, Mandarin also retains the medials, where /i/ and /y/ can occur, as can be seen in the examples above. Cantonese had lost its medials sometime ago in its history, reducing the ability for speakers to distinguish its sibilant initials.

In modern-day Hong Kong, many younger speakers are unable to distinguish between certain phoneme pairs and merge one sound into another. Although that is often considered as substandard and is denounced as being "lazy sounds" (懶音), it is becoming more common and is influencing other Cantonese-speaking regions. (See Hong Kong Cantonese
