What term describes something that is stealthy, secret, or intended to escape observation?

The term that refers to something stealthy, secret, or intended to escape observation is "surreptitious." This word captures the essence of actions or behaviors that are done in a hidden or clandestine manner, often because they are meant to avoid detection or scrutiny. It is commonly used to describe activities that are sneaky or covert, such as surreptitious glances, actions taken without the approval of others, or information gathered discreetly.

In contrast, surveillance refers to the act of monitoring or observing, which does not imply secrecy in the same way. Transcendent describes something that goes beyond ordinary limits or experiences, often related to spirituality or superior quality, and does not relate to stealthiness. Usable simply refers to something that can be used or is practical, having no connection to secretive behaviors or intentions. Understanding the specific meaning and context of "surreptitious" is essential for accurately conveying its implications in various situations.
