Modeemeissa

Modeemeissa is a Finnish grammatical form, specifically the inessive plural of the noun modeemi, meaning modem. The term literally translates to “in the modems” and is used to indicate location inside multiple modem devices. It illustrates how Finnish marks location through cases, with the plural inessive ending -eissa/-eissä depending on vowel harmony.

Morphology and usage: The base word modeemi refers to a modem, a device that modulates and demodulates digital signals for data transmission. In the inessive plural, the word becomes modeemeissa, signaling that something applies to or exists inside several modems. This form is common in technical and telecommunications contexts when describing equipment racks, network configurations, or device-specific data within multiple modems. It contrasts with other forms such as modeemit (nominative plural, the modems) or modeemeihin (into the modems).

Examples:

- Tiedonsiirto tapahtuu modeemeissa. (Data transmission occurs inside the modems.)

- Vikadiagnostiikka suoritetaan modeemeissa tällä hetkellä. (Diagnostics are being performed within the modems at the moment.)

Notes: Modeemi is a loanword from English modem, integrated into Finnish inflection. Modeemeissa is one of several case forms used to discuss location with plural devices, and it is primarily found in technical writing or documentation rather than everyday language.
