minisub
Noun: A small submersible vessel designed to carry one or two persons, used primarily for naval operations or underwater exploration.
The term "minisub" specifically refers to a compact, manned underwater vehicle. It is used in contexts discussing specialized underwater missions where larger submarines are impractical.
- The research team used a minisub to study the coral reef at depths unreachable by divers.
- Naval forces deployed a minisub for a covert reconnaissance mission near the harbor.
- During the documentary filming, the crew captured footage from inside a two-person minisub.
The word is a compound noun ("mini" + "sub"). In technical or military writing, it may be used to emphasize the small scale and specific, often tactical, purpose of the vessel compared to standard submarines.
- Minisubmarine: A less common, full-form variant with the same meaning.
- Submersible: A broader term for any underwater vessel, which can include minisubs, ROVs (Remotely Operated Vehicles), and other craft.
- DSV (Deep Submergence Vehicle): A technical classification that can include certain types of minisubs designed for extreme depths.

The core meaning is defined by its small size (mini) and its function as a submersible (sub). Its use is almost exclusively tied to practical, operational contexts in marine science, exploration, or defense, rather than recreational diving.
