The word moor has two completely different meanings:

1. A stretch of open, rolling land covered with low grasses, heather, and shrubs, usually found in cool, rainy regions. The moors of England and Scotland are wild, windswept places where few trees grow and the weather changes quickly. In The Secret Garden, the Yorkshire moors stretch for miles around Misselthwaite Manor, mysterious and beautiful. Moors can feel lonely and remote, but they have their own stark beauty, with purple heather blooming in late summer and birds calling across the empty landscape.
2. To secure a boat by tying it to a dock, anchor, or buoy so it doesn't drift away. Sailors moor their boats when they reach the harbor, using thick ropes to fasten them safely. You might see fishing boats moored at the pier, bobbing gently but staying put. If a boat isn't properly moored, it could drift out to sea or crash against the dock during a storm. The place where boats are tied up is called a mooring spot.
