A pointed area of land sticking out into the sea is called a cape or promontory.

Here's a breakdown:

* Cape: This is the most common term for a pointed piece of land extending into the sea. It's often used interchangeably with "promontory".

* Promontory: This term emphasizes the height and prominence of the land feature. It's often a steep cliff or rocky outcrop.

Both terms describe a similar feature, but "promontory" suggests a more dramatic and imposing landform.
