This question concerns a phonologically bound verbal marker that signals that the verb has a beneficiary. The marker could be analyzed in the language-specific case as voice, indexing or a 'bound pronoun'. In some languages, applicative markers may be used to topicalize, focalize or background a beneficiary. This type of marking also counts for this feature. The marker does not have to index the beneficiary. Autobenefactive markers do not count and serial verb constructions that include a benefactive verb (typically 'give') do not count.
Arabana (ISO 639-3: ard, Glottolog: arab1267)
In Arabana, the general transitivizer -la- functions, amongst others, as a benefactive marker. Arabana is coded 1.
Thudni-la-thira cry-BEN-PUNCT ‘(They) cry over someone.’ (Hercus 1994: 150) Thanta wirra-la-rnda stuff buy-BEN-PRS ‘(Father) buys dress material for (them).’ (Hercus 1994: 150)
Jina (ISO 639-3: jia, Glottolog: jina1244)
In Jina, a bound beneficiary pronoun may co-occur in a clause with a co-referential full noun phrase. Jina is coded 1 for this feature.

In continuous aspect clauses, indirect object pronouns are infixed inside a reduplicated verb (reduplication marks continuous aspect). This counts as indexing.
