IPA: //nɒnˈɪntəˌkɔːrs//
KK: /nɑnˈɪntərˌkɔrs/
Describing something that opposes or prevents trade or interaction between people or countries.
The government implemented nonintercourse policies to restrict trade with certain nations.
Nonintercourse → It is formed from "non-" (meaning not) and "intercourse" (from Latin "intercurrere", meaning to run between or to communicate). The word "nonintercourse" means the absence of communication or interaction between parties.
Think of 'not' ('non-') having any 'communication' ('intercourse') — that's why nonintercourse means no interaction.
