The ethnic label Zinjibari in Omani society has various connotations that depend on who is using the term and about whom it is being used. Through participant observation and within the context of ethnolinguistic identity theory, this qualitative study aims to demonstrate how the label Zinjibari can function as an outgroup or ingroup label, as a mark of solidarity, as a term of prestige or as a slur. It is also proposed that these different connotations influence language choice among Oman’s Swahili speakers.
