Turvakeskusi
Turvakeskusi is a form that appears to be a nonstandard or mistaken possessive of the Finnish noun turvakeskus, which means “safety center” or “security hub.” The standard Finnish noun turvakeskus is a compound of turva (safety, protection) and keskus (center). In Finnish, possessive forms are created by adding a suffix to the noun; for the second person singular possessive, the correct form attached to turvakeskus is turvakeskuksesi (your safety center). Therefore, turvakeskusi is not typically used in standard Finnish.
In ordinary usage, turvakeskuksesi would be used in a sentence to indicate ownership, for example: Turvakeskuksesi
Notes and related terms: Turvakeskus as a noun can denote a facility, organization, or system that centralizes
