inlet
small arm of water / intake opening
Noun
pl: inlets
This term describes a point of entry, whether natural or mechanical. In a geographical sense, it evokes a sheltered, calm area of water that cuts into a coastline, providing a natural harbor or a secluded passage away from the main current. In technical contexts, it refers to a specific aperture designed for intake. This usage is strictly functional, focusing on the flow of substances into a system, contrasting with an outlet where materials exit.
