Sinhalese spoken in the Southern Province (Galle, Matara and Hambantota Districts) uses several words that are not found elsewhere in the country; this is also the case for the Central and North-Central Provinces and south-eastern region (Uva Province and the surrounding area). In Sinhalese there is distinctive diglossia, as in many languages of South Asia.
There are several cases of vocabulary doublets, e.g.
the words mässā ("fly") and mäkkā ("flea"), which both correspond to Sanskrit makṣikā but stem from two regionally different Prakrit words macchiā and makkhikā (as in Pali).
The grammar lists naramba (to see) and kolamba (fort or harbour) as belonging to an indigenous source.
Kolamba is the source of the name of the commercial capital Colombo.
It is now spoken by a few families in Macau and in the Macanese diaspora.
The language developed first mainly among the descendants of Portuguese settlers who often married women from Malacca and Sri Lanka rather than from neighbouring China, so the language had strong Malay and Sinhalese influence from the beginning.The children are taught the written language at school almost like a foreign language. Most slang were regarded as taboo and most was frowned upon as non-scholarly.However, nowadays Sinhalese slang, even the ones with sexual references are commonly used among younger Sri Lankans.Sinhalese is one of the official and national languages of Sri Lanka.Sinhalese, along with Pali, played a major role in the development of Theravada Buddhist literature.The most important difference between the two varieties is the lack of inflected verb forms in the spoken language.
