What does numb mean?
Numb describes a loss of sensation or emotional responsiveness. A person may say that a body part has gone numb because of intense cold, pressure, injury, or a medical condition, meaning that it can no longer feel pain or touch. The word also has important figurative uses: someone can be numb to suffering, criticism, or a repeated experience, indicating that the impact has faded or that they no longer react strongly. This figurative use can describe emotional shock, trauma, fatigue, or deliberate self-protection. In ordinary conversation, numb is concise and understandable, while formal writing may choose insensitive, unresponsive, or desensitized for greater precision. It is also important not to ignore persistent numbness, because it can indicate nerve damage or circulation problems.
Lacking sensation or the ability to feel pain, especially because of cold, injury, shock, or impaired nerves.
