Delitescent, a rare and difficult-to-pronounce term, refers to something or someone that is concealed or lying hidden away. To get around using this word in everyday conversation, you could employ synonyms such as obscured, camouflaged, or secreted; each of which implies a degree of concealment. Submerged, secluded, or latent all allude to something that is hidden just below the surface, waiting to be discovered. If you want to suggest something that has been purposefully and expertly hidden, concealed, or disguised, you could say it is covert, undercover, or disguised. Whatever term you choose, let it add some mystery and intrigue to your language.
