   • Capable of being submerged in water: Describes an object designed to operate while completely underwater or to withstand being placed underwater without damage.
   • Functioning while submerged: Specifically indicates that a device or vehicle is engineered to work correctly when immersed in water.

2. Noun:

   • A type of underwater vessel: A small craft or warship designed for operation beneath the surface of the water, often for research, exploration, or military purposes.
   • Underwater apparatus or equipment: Any device or piece of machinery intended for use under water.

Usage Examples

• Adjective:

  • The deep-sea exploration was conducted using a manned submersible launched from the mothership.
