Tunkeilijoilta

Tunkeilijoilta is a Finnish grammatical form derived from the noun tunkeilija, meaning intruder. In everyday and technical Finnish it functions as the elative plural form, indicating origin or source, i.e., “from intruders.” It is commonly used in contexts where security, defense, or exclusion is being described.

Linguistic note: tunkeilijoilta is formed from the plural stem tunkeilijat plus the elative plural suffix -ilta/-iltä. The elative meaning conveys movement away from or exclusion by the intruders, and it often appears in constructions that describe protection or prevention related to intruders.

Usage: The expression is typical in safety, law enforcement, cybersecurity, and building security discourse. It can denote actions aimed at preventing intrusion or describing threats that originate with intruders. Examples include sentences such as “Järjestelmä on suunniteltu estämään tunkeilijoilta pääsy,” meaning the system is designed to block access from intruders, or “Toimenpiteet ovat tiivistetty tunkeilijoilta suojautumiseksi,” indicating measures to shield against intruders.

Note: tunkeilijoilta is a specialized form primarily used in formal or technical Finnish. In non-technical prose, the same idea may be expressed with more general phrasing such as “tunnisteita vastustamaan tunkeilijoita” or “estämään tunkeilijoiden pääsyn.”
