infiltrate

Definition

To secretly sneak into an organization, territory, or group where you're definitely not welcome—basically the tactical version of party-crashing. In military and intelligence contexts, it means penetrating enemy lines or organizations covertly, while in medicine it refers to unwanted substances sneaking into body tissues. The goal is always the same: get in undetected, whether you're a spy, a soldier, or a rogue cell.

Example Usage

The undercover agent spent two years working to infiltrate the arms trafficking network.
