niestää
Niestää is a Finnish verb that translates to "to incubate" or "to hatch" in English. It is primarily used in the context of birds laying eggs and sitting on them to maintain a suitable temperature for embryonic development. The act of niestää involves the parent bird, typically the female, remaining on the nest for extended periods, covering the eggs with its body to provide warmth. This is a crucial stage in the reproductive cycle of birds, ensuring the survival of the offspring.
The term can also be used more metaphorically to describe a period of slow development or gestation
