This document discusses language and identity through examining indexicality and markedness. It provides context on Amhara Muslims in Ethiopia who face an identity crisis due to the strong association of their Amharic language with Christianity. It also examines the Speak Mandarin Campaign in Singapore, noting how Mandarin has risen to an unmarked position among Chinese Singaporeans, implying other Chinese varieties are somehow "less Chinese". The document discusses how identity involves both discovering and inventing similarities between social groups, and how markedness establishes a power hierarchy among social categories.
