Ausbau processes increase differences between two close written language varieties. Finnish and Kven are considered two ausbau languages today, in contrast to an earlier view which considered Kven to be a dialect of Finnish. In this article, ausbau processes are illustrated by comparing the use of eera verbs, a group constituting international and Scandinavian loanwords in the two languages. Most eera verbs were purged from Modern Written Finnish and they are expressed via other means today. By contrast, Kven accepts eera verbs in the same way as Old Written Finnish. Purism – perceived as avoidance of certain linguistic elements – is the explanation behind ausbau processes in this case, and purist attitudes reflect the identities of language planners. Eera verbs represent a small corner of language, yet their use differentiates Kven from Modern Written Finnish, and underscores the independence of Kven as a separate language.
