Also Gedagedtiza- ‘companion, one who goes along; a business friend or partner’ . This comparison was proposed by Geraghty (1990:76). However, it is in competition with POc *tuaka ‘elder same sex sibling’, and since *k was lost intervocalically in at least some forms in each of the above languages and in most of the languages used to support *tuaka, it is possible that the two sets should be united under a single reconstruction *tuRaka, a proposal that would have the added advantage of explaining the length of the final vowel in Tolaiturā-. However, unambiguous evidence of *tuRaka remains elusive.
