This study attempts to prove that the SVO order has gained a dominant position in the grammatical evolution in Singapore Chinese language. The theory of the 15 internal relations in the VO-OV order (Dryer, 1992, 2008; Haspelmath, 2005) in linguistic typology as well as other related studies are applied. Taking a historical and geographical point of view, the study also adopts Heine and Kuteva's (2005) narrowing theory in grammatical replication in language contact. It illustrates that the inclination to use the SVO order in Singapore Chinese language is mainly due to an inheritance of language order from the Southern Chinese dialects and the influence exerted by the SVO order in English and Malay language.
