The alphabet used to spell the name also discriminates. Muslims use the Latin alphabet, while Serbs follow the Cyrillic form of writing. Spiritual expressions differentiate as well. A Catholic crosses himself with two fingers, left to right. An Orthodox Serb will make the sign of the cross using three fingers, right to left.
Catholics build their churches on a north-south axis.
Orthodox believers construct theirs east to west. Even without a sense of direction, you can see differences in domes, spires, and minarets. Then there are the roof lines of older homes. Croat houses have a single gable roof. The Muslim roofs come from four different sides, emerging as a single point at the top.
