* Third-degree murder (or manslaughter): This is a less serious form of murder than first- or second-degree murder. The exact definition varies by jurisdiction, but generally involves an unlawful killing that is neither premeditated nor committed with malice aforethought, but is still a reckless or negligent act that results in death. Examples might include causing a death through gross negligence in operating a vehicle or causing death during the commission of a felony.
* Third-degree felony: This refers to the classification of a crime as a felony of a certain severity. The specific penalties (prison time, fines) associated with a third-degree felony vary greatly depending on the jurisdiction (state or federal). It's generally a less serious felony than a first or second-degree felony.
* Third-degree burns: While not directly a legal term, the severity of burns is often relevant in legal cases (e.g., assault, negligence). A third-degree burn is a full-thickness burn, destroying all layers of skin and possibly underlying tissues. The severity of such an injury can be a major factor in determining culpability and sentencing.
* "The Third Degree" (colloquial): This is an informal term referring to aggressive interrogation techniques used by law enforcement, often implying coercion or brutality to obtain a confession. This is generally considered unethical and, depending on the specifics, illegal.
Therefore, the meaning of "3rd degree" in a legal context is highly dependent on the surrounding circumstances. You need more context to understand its precise meaning in a particular situation.
