This study employs tape-recorded data from interviews with elder speakers of Hawaiian conducted in the year 1970 to describe how a specific feature of the Hawaiian language, the first-person inclusive plural pronoun k akou, may be used in discourse as a resource for making claims of ownership on behalf of Hawaiians. To do so, the analysis first invokes Hanks's (2005) notions of deixis and deictic field to show how k akou can create a sense of community among speakers of Hawaiian. Insights from membership category analysis (Sacks 1992;Sacks and Schegloff 1979;Schegloff 2007) are then drawn on to demonstrate how k akou can be interpreted in interaction as a reference to the category of "Native Hawaiian" and how that category can be used to construe specific natural resources, activities, and forms of language as part of a Hawaiian identity. Discussion of the analysis centers on the status of Hawaiian as an endangered language in the midst of a revitalization movement where language and culture have been points of contestation. Usage of k akou to claim ownership is seen as a resource that can allow speakers of Hawaiian to work through the language itself to negotiate what it means to be "Native Hawaiian."
