laitteellaan

Laitteellaan is a Finnish grammatical form meaning “on his/her/its device” and, in context, can indicate that an action or data pertains to the possessor’s device. It is a fused form created by taking laite (device), adding the adessive case ending -lla to mean “on/at,” and attaching the third-person possessive suffix -nsa/ -nsä to indicate ownership by the subject of the sentence. The result is a single word that encodes both location and possession.

Usage notes:

Laitteellaan is most common when the possessor is a third-person singular subject (he/she/it) or a generic singular subject. It is used in everyday language to specify that something occurs on or belongs to the person’s device, which is a frequent reference point in technology, privacy, and digital-context discussions. For other possessors, Finnish has analogous forms, such as laitteellani for “on my device” and laitteellasi for “on your device,” with corresponding variants for other persons and numbers.

Example:

Käyttäjä voi muokata asetuksia laitteellaan. (The user can modify settings on their device.)

Sovellus pyytää pääsyä kameraan laitteellaan. (The app requests access on its device / on the user’s device, depending on context.)

This word reflects Finnish’s richer suffixal morphology, where location (adessive) and possession (person/number) are combined into a single form.
