Ryder

This name derives from an occupational surname, from the Old English pre-7th-Century term “rīdere” meaning “mounted warrior, knight or a messenger”. After the Norman conquest of 1066 and the introduction of their feudal system, the term “Rider / Ryder” was soon replaced by “Knight” in its growing sense of a knight, destined to serve his lord a soldier on horseback. This name derives from the compound “ride +‎ -er”, from the Old English and Proto-Germanic “rīdan / *rīdaną” (to transport oneself by sitting on and directing a horse, later also a bicycle, etc.) plus “-er” (person or thing that does an action indicated by the root verb).
