"چهار" is the Persian word for the number four. It is a cardinal number that comes after three and before five. In various cultures, the number four often symbolizes stability and balance, as it is associated with the four cardinal directions: شمال (north), جنوب (south), شرق (east), and غرب (west). In mathematics, four is an even number and can be represented in various forms, such as رومی (Roman numeral IV) or هندسی (geometric shapes like a square). It is also significant in many traditions, often appearing in folklore and mythology, where it may represent completeness or wholeness.
