What does "tacit" mean?

The term "tacit" refers to something that is implied or understood without being openly expressed. It conveys a sense of agreement, consent, or knowledge that exists without the need for explicit communication. For instance, a tacit agreement might be one where all parties understand the terms through their actions or context rather than through formal discussion. This implicit understanding is a key element of the definition, making it an accurate representation of the word.

In contrast, options referring to clearly expressed elements or redundancy do not align with the nuanced meaning of "tacit," which fundamentally hinges on the absence of spoken or written clarity. Similarly, the vividness described in one of the other choices does not relate to the concept of implied understanding. Thus, "implied or unspoken" fits perfectly with the definition of "tacit."
