Finnish

Etymology

Formally -ise- +‎ -taa, i.e. extracted from verbs originally formed by the suffix -taa from adjectives ending in -inen : -ise-. This reanalysis has likely been further supported by verbs such as altistaa, kaunistaa, tiivistää, valmistaa, based on adjectives of loan origin which show -is even in the nominative.
