Which term indicates something that is fully and clearly expressed?

The term that indicates something fully and clearly expressed is "explicit." When information is described as explicit, it means that it is stated clearly and in detail, leaving no room for confusion or uncertainty. This clarity allows the audience to understand the message without needing to interpret or infer any hidden meanings.

In contrast, alternatives like "ambiguous," "implicit," and "vague" all suggest some level of uncertainty or lack of clear expression. Ambiguous refers to something that can be understood in more than one way, making it unclear. Implicit describes something that is not directly stated but rather implied, which requires interpretation from the audience. Vague indicates a lack of precision or definiteness, which again leads to potential confusion. Thus, "explicit" stands out as the term that conveys clear, precise communication.
