Code mixing is an unconscious process that establishes communication in a multilingual community. The analysis in hand explores code-mixing in the novel “The Holy Woman” by “Qaisra Shahraz”. The research signifies the socio-economic and cultural life of Sindh, Karachi, and other communities living in Tanda Adam, Chiragpur, Hyderabad, Cairo, the city of Aswan, and Jeddah. The ceremony of marriage has been analyzed for words such as wonderful Rishta, three talaqs, sister’s Mehandi, salami presents, the Mela, Nikkah ceremony, and jahez. Through code-mixing and local words, the author depicted not only languages but also highlighted Pakistani culture. The researcher found the writer spots the light on the regional varieties that sound more familiar to the readers and Pakistani English to fulfill the lexical gap because sometimes we do not find proper words in Standard English. The writer has used the words frequently in the novel to actualize the inherent culture of society and describe socio-cultural realities. The data has been analyzed through Baumgardner, Kennedy, and Shamim's (1993) and Kachru's (1983) model of code-mixing. The researcher has found 400 words (English-Urdu words) in the thirty-two semantic contexts. The data has been analyzed through Baumgartner et al (1993) which extends Kachru (1983). The novelist has mixed Urdu words with the English language where it is needed because of the contextual cultural differences, social norms, values, beliefs, ideas, customs, and traditions of the society; and stress the importance of Pakistani English with distinct linguistic features.
