Hong Kong Cantonese (Chinese:香港粵語) is a dialect of the Cantonese language commonly spoken in Hong Kong, as well as Macau. Although the Hong Kong people largely identify this variant of Chinese with the term "Cantonese" (廣東話), a variety of publications in Mainland China describe the variant as Hong Kong speech (香港話).
There are slight differences between the pronunciation used in Hong Kong Cantonese and that of the Cantonese spoken in the neighbouring Chinese province of Guangdong, where Cantonese (based on the Guangzhou dialect) is a main lingua franca.
Over the years, Hong Kong Cantonese has also absorbed foreign terminology and developed a large set of Hong Kong-specific terms. These differences from the Guangzhou dialect are the result of British rule between 1841 and 1997, as well as the closure of the Hong Kong-China border immediately after the establishment of the People's Republic of China in 1949.
History
Before the arrival of British settlers in 1842, the inhabitants of Hong Kong mainly spoke the Dongguan-Bao'an (Tungkun–Po'on) and Tanka dialects of Yue, as well as Hakka and Teochew. These languages and dialects are all remarkably different from Guangzhou Cantonese.
After the British acquired Hong Kong Island, Kowloon Peninsula and the New Territories from the Qing between 1841 (officially 1842) and 1898, large numbers  of merchants and workers came to Hong Kong from the city of Canton, the main center of Cantonese. Cantonese became the dominant spoken language in Hong Kong. The frequent migration between Hong Kong and mainland Cantonese-speaking areas did not cease up until 1949, when the Communists took over Mainland China. During this period, the Cantonese spoken in Hong Kong was very similar to that in Canton.
In 1949, the year that the People's Republic of China was established, Hong Kong saw a large influx of refugees from different areas of mainland China. The Hong Kong Government closed the border  to halt the massive influx, but illegal immigration from Mainland China into Hong Kong continued. Because of this, the correspondence between language and ethnicity may generally be true though not absolute, as many Chinese who speak Hong Kong Cantonese may come from other areas of China, especially Shanghai or non-Cantonese regions of Guangdong where Hakka and Teochew prevail.
Movement, communication and relations between Hong Kong and mainland China became very limited, and consequently the evolution of Cantonese in Hong Kong diverged from that of Guangzhou. In Mainland China, the use of Mandarin as the language of official use and education was enforced. In Hong Kong, Cantonese is the medium of instruction in schools, along with written English and written Chinese.
And because of the long exposure to English during the colonial period, large number of English words were loaned into Hong Kong Cantonese, e.g. "巴士" (/páːsǐː/), literally, "bus". Hong Kong people even started to calque English constructions, for example, "噉 (咁) 都唔 make sense" (literally, "it still does not make sense."). Therefore, the vocabularies of Cantonese in Mainland China and Hong Kong substantially differed.
Moreover, the pronunciation of Cantonese changed while the change either did not occur in mainland China or took place much slower. For example, merging of initial /n/ into /l/ and the deletion of /ŋ/ were observed. Due to the limited communication between Hong Kong and mainland China, these changes only had a limited effect in mainland China at that time. As a result, the pronunciation of Cantonese between Hong Kong and mainland China varied, and so native speakers may note the difference when listening to Hong Kong Cantonese and mainland China Cantonese.
Hong Kong-based Cantonese can be found in Hong Kong popular culture such as Hong Kong films and Hong Kong pop music (Cantopop). Hong Kong people who have emigrated to other countries have brought Hong Kong Cantonese to other parts of the world.
Pronunciation
In modern-day Hong Kong, many native speakers are unable to distinguish between certain phoneme pairs, causing them to merge one sound into another. Although this is often considered substandard and is frequently denounced as "lazy sound" (懶音), the phenomenon is becoming more widespread and is influencing other Cantonese-speaking regions. Contrary to popular opinion, some of these changes are not recent. The loss of the velar nasal (/ŋ/) was documented by Williams (1856), and the substitution of the liquid nasal (/l/) for the nasal initial (/n/) was documented by Cowles (1914). 
List of observed shifts:[2]
Merging of /n/ initial into /l/ initial.
Merging of /ŋ/ initial into null initial.
Merging of /kʷ/ and /kʷʰ/ initials into /k/ and /kʰ/ when followed by /ɔː/. Note that /ʷ/ is the only glide (介音) in Cantonese.
Merging of /ŋ/ and /k/ codas into /n/ and /t/ codas respectively, eliminating contrast between these pairs of finals (except after /e/ and /o/): /aːn/-/aːŋ/, /aːt/-/aːk/, /ɐn/-/ɐŋ/, /ɐt/-/ɐk/, /ɔːn/-/ɔːŋ/ and /ɔːt/-/ɔːk/.
Merging of the two syllabic nasals, /ŋ̩/ into /m̩/, eliminating the contrast of sounds between 吳 (surname Ng) and 唔 (not).
Merging of the rising tones (陰上 2nd and 陽上 5th).[3]
Today in Hong Kong, people still make an effort to avoid these sound merges in serious broadcasts and in education. Older people often do not exhibit these shifts in their speech, but some do. With the sound changes, the name of Hong Kong's Hang Seng Bank (香港恆生銀行), /hœ́ːŋ  kɔ̌ːŋ  hɐ̏ŋ  sɐ́ŋ  ŋɐ̏n hɔ̏ːŋ/, becomes /hœ́ːn kɔ̌ːn hɐ̏n sɐ́n  ɐ̏n hɔ̏ːn/, sounding like Hon' Kon' itchy body (痕身 /hɐ̏n sɐ́n/) 'un cold (UN寒 /ɐ̏n hɔ̏ːn/) . The name of Cantonese itself (廣東話, "Guangdong speech") would be /kʷɔ̌ːŋ  tʊ́ŋ  wǎː/ without the merger, whereas /kɔ̌ːŋ  tʊ́ŋ  wǎː/ (sounding like "講東話": "speak eastern speech") and /kɔ̌ːn tʊ́ŋ  wǎː/ (sounding like "趕東話": "chase away eastern speech") are overwhelmingly popular.[4]
The shift affects the way some Hong Kong people speak other languages as well. This is especially evident in the pronunciation of certain English names: "Nicole" pronounce [lekˈkou̯], "Nancy" pronounce [ˈlɛnsi] etc. A very common example of the mixing of (/n/) and (/l/) is that of the word 你, meaning "you". Even though the standard pronunciation should be (/nei/), the word is often pronounced (/lei/), which is the surname 李, or the word 理, meaning theory. The merger of (/n/) and (/l/) also affects the choice of characters when the Cantonese media transliterates foreign names. 
Prescriptivists who try to correct these "lazy sounds" often end up introducing hypercorrections. For instance, while attempting to ensure that people pronounce the initial /ŋ/, they may introduce it into words which have historically had a null-initial. One common example is that of the word 愛, meaning "love". Even though the standard pronunciation would be /ɔ̄ːi/, but the word is often pronounced /ŋɔ̄ːi/.
In recent years, a number of Hong Kong secondary schools have tried to reverse this change by making the learning of Cantonese Pinyin part of the school Chinese curriculum.
Unique phrases and expressions

Due to Hong Kong's unique historical background, Hong Kong Cantonese has evolved differently from the Mandarin spoken in China, Taiwan and Singapore over the years. Hong Kong Cantonese has developed a number of phrases and expressions that are unique to the context of Hong Kong. These phrases and expressions usually make references to specific things that can only be found in Hong Kong or specific incidents that happened in Hong Kong.
Here are a few examples:

Here, the former refers to Hong Kong's status as a British colony, where prisoners are detained on behalf of the Sovereign, and is similar to the English colloquial expression "guest of Her Majesty" / "live at Her Majesty's pleasure". The latter refers to the transfer of sovereignty of Hong Kong to China in 1997. The situations alluded to are both unique to Hong Kong.
Loanwords
Life in Hong Kong is characterised by the blending of Asian (southern Chinese in particular) and Western cultures, as well as the city's position as a major international business centre. In turn, Hong Kong influences have also spread widely into other cultures. As a result, a large number of loanwords are created in Hong Kong and then exported to Mainland China, Taiwan, Singapore, and Japan. Some of the loanwords have become even more popular than their Chinese counterparts, in Hong Kong as well as in their destination cultures.

Code-switching and loanword adaptation

Hong Kong Cantonese has a high number of foreign loanwords. Sometimes, the part of speech of the incorporated words are also changed, like "佢地好friend", translated into English as "they are very 'friend'", means "they are good friends". The word "friend" is changed from a noun into an adjective. In some examples, some new meanings of English words are even created. For example, "至yeah", literally "the most yeah", means "the trendiest". Originally, "yeah" means "yes/okay" in English, but it means "trendy" when being incorporated into Hong Kong Cantonese (see also "yeah baby" and "aww yeah").
Semantic change is common in loanwords; when foreign words are borrowed into Cantonese, polysyllabic words and monosyllabic words tend to become disyllabic, and the second syllable is in the Upper Rising tone (the second tone). For example, "kon1 si2"  (coins), "sek6 kiu1" (secu</b>rity) and "ka1 si2" (cast). A few polysyllabic words become monosyllabic though, like "mon1" (mon</b>itor), literally means computer monitor. And some new Cantonese lexical items are created according to the morphology of Cantonese. For example, "laai1 記" from the word "li</b>brary". Most of the disyllabic words and some of the monosyllabic words are incorporated as their original pronunciation, with some minor changes according to the Cantonese phonotactics.
Incorporating words from foreign languages into Cantonese is also acceptable by most Cantonese speakers. Hong Kong Cantonese speakers frequently code-mix although they can distinguish foreign words from Cantonese ones. For instance, "噉都唔 make sense", literally means "that doesn't make sense". After a Cantonese speaker decides to code-mix a foreign word in a Cantonese sentence, syntactical rules of Cantonese will be followed. For instance, "sure" (肯定) can be used like "你 su1 唔 su1 aa3?" (are you sure?) as if it were its Cantonese counterpart "你肯唔肯定?", using the A-not-A question construction.
In some circumstances, code-mixing is preferable because it can simplify sentences. For example, Instead of code-switching and using "check-in" in expressions like 你check咗in未？(nei5 cek1 zo2 in6 mei6 aa3, 'Have you checked in yet?'), people will have to use the pure Cantonese expression 辦理登機手續 (baan6 lei5 dang1 gei1 sau2 zuk6 'check in (on a plane)' ), which contains six syllables.[7]
