What word signifies something that is indicated by necessary connotation though not expressed directly?

The word that signifies something indicated by necessary connotation though not expressed directly is "tacit." This term refers to an understanding or agreement that is implied without being openly stated. In contexts such as communication or social interactions, a tacit acknowledgment or consent conveys that something is understood implicitly.

For example, when someone nods in agreement without verbal confirmation, that non-verbal cue demonstrates tacit approval. This is particularly relevant in situations where direct expression may be avoided or unnecessary, yet the meaning is clear through context or shared understanding.

In contrast, "explicit" refers to something clearly and directly stated, leaving no room for doubt; "conspicuous" indicates something that is easily seen or noticed; and "apparent" denotes something that is obvious or easily understood. None of these terms capture the essence of indirect communication or implied meaning that "tacit" conveys.
