The term "ματάκι" (pronounced "mataki") refers to a small charm or amulet in Greek culture, often used to protect against the "evil eye" or μάτι (mati). The evil eye is a belief that certain individuals can cause harm or misfortune through their envious or malevolent gaze. The charm is typically blue and shaped like an eye, symbolizing protection and good fortune. In Greek tradition, the ματάκι is commonly worn as jewelry or displayed in homes. It serves as a talisman to ward off negative energy and is believed to bring blessings. Many people in Greece and other cultures use similar protective symbols to counteract the effects of envy and ill will.
