kertaluontoisesti

Kertaluontoisesti is a Finnish adverb that translates to "once," "singularly," "uniquely," or "on a one-off basis" in English. It describes an event or action that happens only once, not to be repeated. The term emphasizes the exceptional or non-recurring nature of something.

For example, a special concert that is advertised as "kertaluontoisesti" implies it will not be part of a regular series or tour. Similarly, a "kertaluontoinen" offer in a store means it is a special deal available only for a limited, single occasion. The adverb is often used to highlight a unique opportunity or a solitary occurrence. It is distinct from adverbs indicating repetition, such as "usein" (often) or "aina" (always). The concept of "kertaluontoisesti" is about singularity and the absence of recurrence.
