In the feature (based on WALS feature 46, by Martin Haspelmath, we look at the form of indefinite pronouns, i.e. expressions rendering 'something' and 'somebody'. These can be expressed by special pronoun forms such as Papiamentu or Spanish algo 'something', or by interrogative-based forms such as Chinuk Wawa íkta 'what; something', or by generic-noun-based forms such as Guinea-Bissau Kriyol un kusa 'a thing, something', or by old generic-noun-based indefinites that continue the English forms something and somebody (e.g. Kriol jamjing, sambadi) but are no longer synchronically analyzable. Finally, languages may use a special existential construction instead of an indefinite pronoun in argument position ('There is who came' for 'Someone came').
