A more thorough explanation:

Definition: Nonintercourse refers to the refusal of one country to engage in commercial dealings with another. It can also refer to the lack of access, communication, or sexual relations between a husband and wife.

Example: The Non-Intercourse Act of 1809 was a congressional act that prohibited the importation of British or French goods. This was a response to the ongoing conflict between the United States and these two countries. By refusing to trade with them, the United States hoped to put pressure on them to change their behavior.

Example: In a marriage, nonintercourse can refer to a lack of sexual relations between a husband and wife. This can be due to a variety of reasons, such as physical or emotional issues, or simply a lack of interest. It is important for couples to communicate openly about their needs and desires in order to maintain a healthy relationship.

Both examples illustrate the concept of nonintercourse - in the first example, it refers to a lack of commercial dealings between countries, while in the second example it refers to a lack of sexual relations between partners. In both cases, there is a lack of interaction or communication that can have negative consequences if not addressed.
