Meaning of Quoin in Urdu

Quoins (/kɔɪn/ or /kwɔɪn/) are masonry blocks at the corner of a wall. They exist in some cases to provide actual strength for a wall made with inferior stone or rubble and in other cases to make a feature of a corner, creating an impression of permanence and strength, and reinforcing the onlooker’s sense of a structure’s presence.
