Which of the following is not a meaning of 'overt'?

The term 'overt' refers to something that is open, observable, or not hidden. It describes actions or behaviors that are visible and easily recognized rather than concealed or kept secret. Therefore, the meanings that align with 'overt' include 'revealed' and 'expressed,' which suggest clarity and visibility.

Choosing 'hidden' as the answer is appropriate because it directly contradicts the essence of what 'overt' means. Something that is hidden is, by definition, not overt, as overt suggests openness rather than secrecy. In contrast, the other meanings—'concealed' implies something that is not visible, while 'revealed' and 'expressed' emphasize clarity and straightforwardness, aligning with the concept of being overt.
