Oppositeinterior
Note
A word that began on the body. Middle English coste meant a rib, a flank or the side of a building, and also a shore, a district, even a division of the heavens. The seaside meaning is the one that lasted. It names the land along the water, so a coast is rocky or flat and runs past places: the coast of Maine, the southern coast.

Note
A figure taken from rolling on without power, like a bike freewheeling downhill: success with the engine off. Unlike doing the bare minimum, it need not be a criticism, though an easy ride can leave someone unready for the harder stretch that follows.

- 5To sail along or close to a shore, keeping near the land rather than crossing open water.

Merchant vessels would coast from port to port.
Note
A sailor's verb, usually without an object: a ship coasts northward, or from port to port. It comes from Middle English costeien, "to travel along a border or coast." John Arbuthnot wrote in 1727 that "the Ancients coasted only," keeping to shores rather than open sea; hug the coastline is the plainer phrase. In older English, it could also take the shore as its object, as in coasting an island, meaning sailing along its edge.
- 6To slide downhill, especially on a sled over snow or ice.
Every winter the kids would coast down Miller's hill on wooden sleds.
On snow days the children would coast down the long hill behind the church until dark.
Similarsled, slide, toboggan, sledge
Note
A winter word from American regional speech, where children coast down a hill on a sled or slide over ice. It shares its physics with the freewheeling sense: gravity, not effort, keeps the sled moving. Outside the regions that use it, readers may picture a bicycle rather than a sled, so in general writing, name the sled to make the meaning clear.

P. Crescentius, in his lib. 1 de agric. cap. 5, is very copious in this subject, how a house should be wholesomely sited, in a good coast, good air, wind, etc.
1624, Democritus Junior [pseudonym; Robert Burton], The Anatomy of MelancholyNote
Here the land needs no sea at all. In Tyndale's New Testament of 1526, Herod kills the children of Bethlehem "and in all the costes thereof." Those coasts are the surrounding inland district. Robert Burton, in The Anatomy of Melancholy, passes on advice that a house be sited "in a good coast, good air," meaning a healthy neighborhood. Older texts read differently with that in mind.

And the Coaſt towards which the lines KL and VX are drawn, may be call’d the Coaſt of unuſual Refraction.
1730, Isaac Newton, OpticksNote
Isaac Newton still used it in his Opticks, naming one side "the Coast of unusual Refraction." It keeps the old sense of "side," from which the shoreline meaning narrowed, a shift French had already made before English took the word. A modern reader will picture a shoreline, so when quoting older scientific writing, gloss it as "side" or "edge."

- 9A region of the air or sky; a part of the heavens.
Note
Spenser's Faerie Queene (1590) shows it at work: Merlin can tell "under what coast of heaven the man did dwell," locating a person by the quarter of sky above him. Middle English coste already covered "division of the heavens" and "compass direction," so the phrase is less fanciful than it looks. Used today, it would read as a deliberate archaism.

1589, Richard Hakluyt, The Principall NavigationsNote
Movement on land, not only by ship. In Shakespeare's Venus and Adonis (1593), Venus "coasteth to the cry," hurrying toward the sound she hears. The idea is approaching or keeping alongside, the Middle English "go alongside, skirt" behind the sailing sense. Hakluyt's 1589 "coasting along" sits on the line between this and the nautical use. Modern readers will need help to recognize it.

- 11To accompany or escort someone along a coast or riverbank, keeping pace beside them.
Note
The person accompanied becomes the object. In Hakluyt's English version of Laudonnière's account of a 1564 French voyage to Florida, the narrator sails up a river "being followed by the Indians, which coasted me a long the river," keeping pace with his boat along the bank. The idea is going alongside someone, close to the "keep beside" meaning. Modern English would say followed or escorted; this transitive use is obsolete.
