the old boy form is given a specific identification for each school. some schools use an adjectival form of the school name, such as "old etonian", "old harrovian", or "old oundelian" (old boys of eton college, harrow school, and oundle school). some use a latin form derived from the latin name of the school or its location as "old novaportan" (old boys of adams' grammar school, newport, shropshire). some are based on the name of the founder, such as "old wykehamist" and "old alleynian" (for old boys of winchester college, founded by william of wykeham, and dulwich college, founded by edward alleyn). some are based on the school's location or street, such as "old gowers" (for university college school, originally in gower street). many of the schools have histories dating back several hundred years, and the old boy forms may have been in use for a hundred years or more. other more recently established schools have devised old boy names that are distinctive to prevent confusion with other schools. the tradition for many girls' schools has been to use the term "seniors" rather than "old girls".
