IPA: /ˌɛkstrəˈtɛrɪˌtɔːrɪəl/
KK: /ɛkstrəˈtɛriəˌtɔriəl/
Relating to a legal jurisdiction that extends beyond the boundaries of a specific territory or country.
The embassy operates under extraterritorial laws, meaning it is not subject to the host country's regulations.
Exterritorial → It is formed from "ex-" (meaning out of or outside) and "territorial" (from Latin "territorium", meaning land or territory). The word refers to something that is outside the jurisdiction of a particular territory or land.
Think of 'outside' ('ex-') of a specific 'land' ('territorial') — that's why exterritorial means something that exists beyond the boundaries of a territory.
