Seofon
Seofon is a term originating from Old English, meaning "seven." It is primarily used as a numeral and appears in historical texts and place names. For instance, the name of the ancient kingdom of Mercia is sometimes written as "Merscware," and its inhabitants were referred to as "Merscware," which can be interpreted as "dwellers of the march" or "dwellers of the seven". In some contexts, it can also refer to a group of seven individuals or items.
The use of "seofon" is most prevalent in early medieval England, particularly during the Anglo-Saxon period.
