kypsyttää

Kypsyttää is a Finnish verb meaning to cause to ripen or to bring to maturity. It is a transitive verb formed from the root kypsy- (to ripen) with the causative suffix -yttää. The corresponding noun forms are kypsytys (the ripening process) and kypsyys (the state of being ripe). The related intransitive verb kypsyä means “to ripen.”

In practice, kypsyttää is used to describe processes that accelerate or complete ripening in agriculture, horticulture, and food production. Ripening can be natural or guided through controlled conditions. Common methods include storage under specific temperature and humidity, exposure to ethylene gas, or aging, depending on the product. For example, banaanit and avokadot are often kypsytetty in controlled environments, and cheese undergoes kypsytys during maturation to develop flavor and texture.

The term can also be used metaphorically to describe guiding a person or a process toward greater readiness or maturity, for instance in educational or developmental contexts.
