2004, it was also Singapore's third most popular free-access tourist attraction, after Orchard Road and Chinatown. Naming conventions Because of their linguistic and religious diversity, Singapore Indians use a variety of naming conventions. Traditionally, most Tamil Hindus place their father's name after their given name, linked by 's/o' (son of) or 'd/o' (daughter of), e.g. 'Ravi s/o Govindasamy'. Similarly, Tamil Muslims have names in the form 'Abdul s/o Rahman' (in contrast to Malay Muslims, who use the connector 'bin' (son of) or 'binte / bte' (daughter of) instead). Likewise, a Tamil Christian name might be Daryl s/o David. The use of these connectors arose during the colonial period. However, this format is somewhat rare today. Often, an individual will reduce their father's name to an initial, hence 'G. Ravi'. This approach is popular among many Singapore politicians, as it simplifies names that, to non-Indian Singaporeans, can be very long, complicated and difficult to pronounce. Thus, the late Senior Minister Sinnathamby Rajaratnam was known as S. Rajaratnam, while late former President Sellapa Ramanathan is known as S.R. Nathan. Likewise, other prominent Indians include S. Dhanabalan, S. Jayakumar and J. B. Jeyaretnam (also known simply as 'JBJ'). Likewise, Tamil Muslims and Christians also use initials in a similar way. This convention is regularly used in South India. Another popular approach is to omit the 's/o' or 'd/o' connector altogether, e.g. 'Ravi Govindasamy'. While the name appears to conform to a Western format, the last name (Govindasamy) technically remains the father's name, and is not the family surname. As such, the individual should properly be addressed as 'Mr Ravi', rather than 'Mr Govindasamy'. However, some people use their father's name as a surname, i.e. Ravi calls himself 'Mr Govindasamy' and uses it as a surname for his children. Instead of naming his son 'Arun (s/o) Ravi', he would name him 'Arun Govindasamy' (or even 'Arun Govind'). This approach is also adopted among several Tamil Christians. Some new surnames have been created in this way. Several South Indians use caste names as surnames in the Western mode. Common examples of such names in Singapore include Iyer and Pillay/mudaliyar (Tamil), Nair and Menon (Malayalee). While Telugu people use caste as the middle name Reddy/Naidu and family name as surname. Some Tamil Christian families have retained Indian names (as given names or 'family' names), generally alongside or in place of Western or Christian names, e.g. Vivian
