painikkeen
Painikkeen is the genitive singular form of painike, a Finnish noun meaning a button, switch, or push-button control. The form is used to show possession or association with a button, as in painikkeen toiminto (the function of the button) or painikkeen väri (the color of the button). In everyday and technical Finnish, painike refers to a control on a device or interface that is intended to be pressed to trigger an action.

The word painike is derived from the verb painaa, meaning “to press,” with a nominalizing suffix -ke.
In contemporary usage, painike and its inflected forms appear frequently in Finnish technical vocabulary. They are
