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.
