Invocations (la'tuk) in the form of benediction of Kallahan ancestors
are constructed from four speech activities: addressing, appealing, gi
ving examples, and argumentation. In addition, they assume shared expe
riences between the speaker and the ancestor personified by a living m
ember of his family. While analogous to normal dialogue, however, thes
e modes exhibit substantial differences: the ancestor does not answer;
the request for beneficence takes place in a feast which itself is th
e result of ancestral munificence, even if this cannot be deduced from
the meaning of the invocation. This article goes on to examine four p
ragmatic concerns that affect the way these Kallahan la'tuk are unders
tood.
