Anything explicit is completely clear and includes details. If you don't want your little brother to become a snake snack, you'll need to give him explicit instructions for feeding your pet boa constrictor safely.
This adjective describes anything that is clear, detailed, and easy to understand. Explicit orders are easy to carry out, and explicit directions are easy to follow. When someone is explicit, they're not beating around the bush or being confusing. Explicit can also mean "offensive" or "graphic," a description that is sometimes included in parental-advisory warnings about "explicit language" or "explicit violence" in movies.
