pipe — verb

Synonym discussion

Sense: noun/1

For noun sense 1, pipe usually suggests a hard hollow part in a fixed system that carries water, gas, or waste. Tube is broader: it can mean a softer container, a body part, or any hollow shape, so it does not always suggest building work or plumbing. Hose is usually flexible and often moved by hand, as in a garden hose or fire hose. Pipeline often means a larger transport line or network, especially for oil or gas over a long distance. So you fix a broken pipe under the sink, water plants with a hose, and discuss a new pipeline across the desert.

Etymology

LatinOld FrenchEnglish

Pipe came into English from Latin through early French forms meaning a tube or flute. Because the basic idea was a narrow hollow shape that air or liquid could move through, English later used the word for smoking tools, musical instruments, organ tubes, and systems that carry water or gas.
