1. Keystone

   A keystone is the wedge-shaped stone piece at the apex of a masonry vault or arch, which is the final piece placed during construction and locks all the stones into position, allowing the arch to bear weight. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, due to its position at the apex. Old keystones can decay due to vibration, a condition known as bald arch. In a rib-vaulted ceiling, keystones may mark the intersections of two or more arched ribs. For aesthetic purposes, the keystone is sometimes larger than the other voussoirs, or embellished with a boss. Mannerist architects of the 16th century often designed arches with enlarged and slightly dropped keystones, as in the "church house" entrance portal at Colditz Castle. Numerous examples are found in the work of Sebastiano Serlio, a 16th-century Italian Mannerist architect.

Examples of KEYSTONE in a Sentence

1. Bernie Sanders:

   Now to me, as opposed to maybe some other unnamed candidates, the issue of Keystone was kind of a no-brainer. It never made sense to me, from day one, as to why you would extract and transport some of the dirtiest fuel on this planet.

2. Gene Karpinski:

   This veto, along with the president’s increasing public skepticism about Keystone XL ... makes us more confident than ever that (the) president will reject the permit itself once and for all.

3. Getty Images:

   We must reverse course and streamline permitting and drop regulations that restrict oil and natural gas production. The Keystone Pipeline would replace Venezuela, Iran, and Russian imports.

   For that I want to apologize, at times we have been portrayed as if we've acted like Keystone Cops.

5. Jason Modglin:

   Keystone would have absolutely made a difference because it would have lowered the cost of Canadian crude to get to the markets that it needs to get to in order to be refined and shipped to be utilized here in the United States, and so by canceling Keystone, it artificially raises the price of Canadian oil and allows for the Russians to undercut that.
