Definition: Kalogirou means "a sign, mark," referring to an important or essential feature that provides clues or significance. It is often associated with a specific symbol or figure in religious texts such as Christianity or Judaism. In ancient Greek, it was used for identification and marking points of importance within religious practices, such as the point where someone places their hands upon while holding a sacred object (such as a cross), or where one holds a sword (the "kalogirou" of a spear). The meaning is that the kalogirou serves as a symbol indicating something significant or important to be remembered or understood.
