A more thorough explanation:

Definition: Adulterine (pronounced uh-duhl-tuh-reen) is an adjective that can mean several things:

1. Something that has been mixed with impurities or other substances, making it less pure or of lower quality.
2. Something that is illegal or not licensed.
3. A person who was born as a result of adultery.
4. Something that involves or relates to adultery, which is when a married person has a sexual relationship with someone who is not their spouse.

There are also two archaic (old-fashioned) uses of the word:

1. Adulterine can be used as a noun to refer to an illegitimate child, which is a child born to parents who are not married to each other.
2. Adulterine guild was a term used in history to describe a group of traders who acted like a corporation without a charter and paid an annual fine for permission to exercise their usurped privileges.

Examples:

• The company was accused of selling adulterine products that contained harmful chemicals.
• The unlicensed doctor was arrested for performing an adulterine surgery.
• The king's adulterine son was not allowed to inherit the throne.
• The novel tells the story of an adulterine affair between two married characters.
• The woman was shunned by society because she was an adulterine bastard.
• The adulterine guild was able to operate without a charter by paying fines to the government.

These examples illustrate the different meanings of the word adulterine. The first two examples show how adulterine can refer to something that is impure or illegal. The third and fourth examples show how adulterine can relate to adultery. The fifth example shows how adulterine can be used as an archaic term for an illegitimate child. The sixth example shows how adulterine guild was a historical term used to describe a group of traders who operated without a charter.
