nappuloihin

Nappuloihin is the illative plural form of the Finnish noun nappula, which denotes a small button, knob, or pin on a device or component. The form combines the stem nappula with the illative plural suffix -iin, indicating movement toward or into multiple buttons or pins. As a grammatical construction, nappuloihin is not a separate concept but a case-inflected form used in sentences to express direction or destination relative to several small controls.

Nappula itself has several everyday meanings. Most commonly it refers to a physical button on a control panel, a key on a keyboard, or a switch on electronic or mechanical equipment. In broader technical contexts, it can also refer to small protrusions, pins, or contact points that resemble a “button” in function or form. The plural nominative form is nappulat, while the partitive plural is nappuloita, used when describing an unspecified amount of buttons being interacted with.

In usage, nappuloihin appears in contexts involving movement toward or insertion into multiple buttons or contact points. For example, it can appear in technical instructions or descriptions of procedures that involve directing attention or action to several controls.
