kuulokkeisiin

Kuulokkeisiin is the illative plural form of the Finnish noun kuulokkeet, meaning headphones. The illative case marks movement toward or destination into something, and in Finnish it is commonly used with verbs of placement or insertion. In practical use, kuulokkeisiin appears in contexts such as instructions, manuals, or technical descriptions where an action is directed toward the headphones.

Usage and meaning

In instructional language, kuulokkeisiin conveys that something is being connected to or moved into the headphones, or that sound is being directed to them. Examples include sentences like "Liitä johto kuulokkeisiin" (Connect the cable to the headphones) and "Siirrä ääni kuulokkeisiin" (Send the sound to the headphones). The form is also found in hardware or software documentation where actions pertain to the headphones as a destination.

Grammar and formation

Kuulokkeet is the plural nominative form; its illative plural, kuulokkeisiin, is formed by adding the illative ending to the stem. This contrasts with the nominative kuulokkeet and other cases such as partitive or inessive. The illative singular would be kuulokkeeseen, while the plural illative remains kuulokkeisiin.

Notes

In everyday speech, speakers may prefer expressions that specify the sense of wearing or using headphones, such as päähän tai korville, rather than focusing on the destination as a physical container. Kuulokkeisiin thus remains a precise term for describing actions directed toward the headphones in technical or procedural contexts.
