Anything explicit is very clear, whether it's instructions or a dirty movie.
Thanks to parental-advisory warnings about "explicit language" or "explicit violence," you might think this word only applies to things that are dirty, naughty, or adult in some way. That is a common meaning of explicit, but it's not the only meaning. This also means anything that is clear and easy to understand. Explicit orders are easy to carry out; explicit instructions are easy to follow. When someone is explicit, they're not beating around the bush or being confusing.
