Hooded means wearing or having a hood, or something that resembles or is shaped like a hood. It can also describe an animal feature or a part of a garment that covers the head or has a hooded appearance. Key senses:

• Clothing: a garment with a hood, such as a hooded jacket or sweat shirt.
• Appearance: having a hood-like shape or covering on parts of the head or neck.
• Animal/biology: features that resemble a hood, such as a hooded cobra or other hood-like structures.

If you want a specific sense (e.g., clothing term, animal-related usage, or a figurative sense), tell me which context you’re interested in and I’ll tailor the explanation.
