IPA: /ˌdʒʊərɪsˈdɪkʃən/
KK: /dʒɜrɪsˈdɪkʃən/
The official power or authority to make legal decisions and judgments, often within a specific area or territory.
The court has jurisdiction over cases involving local laws.
Jurisdiction → It is formed from "jus" (meaning law) and "dictio" (meaning saying or declaration). The word refers to the authority to declare or enforce the law.
Think of 'law' ('jus') being 'declared' ('dictio') — that's what jurisdiction means, the authority to declare the law.
