What does tideway mean?
A tideway is a nautical and geographical term for a channel or stretch of water through which the tide flows, especially one separating a coast from an offshore island. It can also refer to a strong tidal current. The expression naturally evokes maritime navigation, since boaters and pilots must account for changing water levels and currents. In British English it is especially familiar in nautical and coastal contexts, although it is also understood in American English. A tideway is not simply a synonym for the tide itself: the tide is the periodic rise and fall of sea level, whereas the tideway is a place or route through which tidal water moves. The word's compact construction makes its meaning memorable: “tide” supplies the moving water, and “way” suggests a passage. In maps, sailing directions, and coastal descriptions, tideway therefore names the meeting of geography and tidal motion.
