Chinese community in Kuching Sarawak is largely composed of Fujian, Chaozhou, and Hakka. The common languages in urban area are Hokkien or Teochew. While a significant number of people speaking Hakka in Kuching area, especially in the rural, such as Batu Kawa district, Bau and Serian. The major ancestral homelands of Hakka in Kuching are Tai Poo, Huiyang, Jiexi, Haifeng, Lufeng, and many other places in Guangdong. Hopo, a dialect of Hakka, spoken in Batu Kawa is always mingled with different tribes and different Chinese dialects due to geographical factors. After a long period of time, its lexicon is highly influenced by ethnic integration and borrowing words from foreign vocabulary. This essay aims to analyze interesting phonological and lexical aspects in Sungai Tapang, being influenced by Malay, English, Chaozhou, and Cantonese. Meanwhile, we analyze Hakka spoken in other countries for comparative studies, for example, those in Singkawang, Indonesia and Linzinei, Taiwan. We find that Hakka dialects used in these two places are pretty similar to Hakka in Sungai Tapang. No one speaks Cantonese in Sungai Tapang, but surprisingly, our analysis reveals that the daily-life vocabulary of Hakka also borrows some words from Cantonese. In this way, it can be assumed that the linguistic changes are affected by immigration and daily language contacts. Furthermore, the Cantonese drama was popular from 1970s to 1990s. Cantonese words were lent to Hakka unconsciously and started to have pervasive usages. If the mother language cannot be learned completely, its tone and phonotactics can be interfered and new vocabulary is generated as a result. The ‘Hakka’ language in Malaysia is unique, and its innovative situation is worth further exploring and better understanding.
