What does the word gainsay mean?

The term "gainsay" specifically means to deny or contradict something. It is often used in contexts where one is refuting a statement or assertion made by another. The prefix “gain-” in this word implies opposition, while the root “say” refers to speaking or asserting something. Therefore, when someone "gainsays" a statement, they are actively stating that it is not true or rejecting it.

In contrast, the other options provide meanings that do not align with this definition. Accepting with enthusiasm suggests agreement rather than contradiction. Creating confusion implies a lack of clarity or understanding, which is unrelated to denying something. Reasoning logically involves the process of drawing conclusions based on sound argumentation rather than contradicting a viewpoint. Thus, the choice that accurately captures the essence of "gainsay" is the one that denotes denial or contradiction.
