What is the meaning of 'covert'?

The term 'covert' signifies something that is intentionally concealed or not made known to others. This aligns perfectly with the idea that covert actions or strategies are those that are not openly acknowledged and are often executed in secrecy. Covert often refers to operations or tasks that are carried out discreetly, without public knowledge, especially in contexts like espionage or intelligence work.

The other options present meanings that are quite different. 'Openly displayed and obvious' contrasts with the essence of covert, which emphasizes secrecy. 'Complicated and difficult to understand' does not relate to the hidden nature of something being covert. Lastly, 'highly regarded and respected' describes a positive perception rather than a hidden or concealed state. Therefore, choosing the definition that emphasizes intentional concealment is entirely appropriate and captures the core meaning of 'covert.'
