embrasure

Chess, by and large, is a war game played by nonmartial people who would have trouble identifying the business end of an M16 or explaining the difference between an embrasure and a sally port.

They can also see gun embrasures in the basement, swords from medieval wars and a passageway, now closed off, that was used as an escape route.

I leaned back in the embrasure in a more comfortable position, so that I could enjoy more fully the aërial gambolling.

Robin’s bedchamber was off the main hall or living room of the house, in an embrasure of the thick wall.

It was a worthy song, and it could stir the embrasures and battlements of a strong man’s soul.
