uskomattoman

Uskomattoman is the genitive singular form of the Finnish adjective uskomaton, meaning “incredible” or “unbelievable.” In Finnish, adjectives normally agree with the noun they modify, and the form uskomattoman appears when the noun is in the genitive case or when it is used as an intensifier before another modifier. As a result, uskomattoman functions as a strong, emphatic descriptor in noun phrases and can appear in combination with other adjectives or with a genitive noun.

Usage examples include phrases such as uskomattoman tarinan loppu, meaning “the ending of an unbelievable story,” where uskomattoman modifies tarinan in genitive. It can also appear before another descriptive word, as in uskomattoman kaunis maisema, commonly rendered in English as “an incredibly beautiful landscape.” The word can be complemented by the adverbial form uskomattomasti, meaning “incredibly,” to modify verbs, adjectives, or entire clauses.

The adjective also has comparative and superlative forms, such as uskomattomampi (more unbelievable) and uskomattomin (the most unbelievable), though these are used sparingly in everyday Finnish. The root idea behind uskomaton is related to belief or disbelief; the term conveys a high degree of astonishment or admiration rather than mere adequacy. In contemporary usage, uskomattoman is widespread across spoken and written Finnish, ranging from informal speech to descriptive prose and journalism.
